Every number in your loan file assumes a tenant who pays. The appraiser writes a market rent opinion, the underwriter divides it into your payment, and the ratio comes out at 1.22 or 1.31 or whatever it comes out at. Nowhere on that worksheet is there a line for whether the person signing the lease has been evicted twice in four years.
That line lives with you. Screening is the one part of a rental deal that is entirely yours to run, entirely unregulated by your lender, and entirely capable of destroying a ratio that underwrote clean. I have watched investors spend six weeks fighting over a quarter point of rate and then hand the keys to the first applicant who had cash for a deposit.
Here is what screening actually consists of, what the law requires you to do when you say no, and what a bad tenant does to the arithmetic that got you the loan.
Your lender screens the borrower, not the tenant
This surprises people. On a purchase of an occupied rental, an underwriter will want the lease and may want an estoppel certificate from the sitting tenant confirming the rent and the deposit. That is a document review. Nobody pulls the tenant’s credit. Nobody checks whether they have a judgment.
On a vacant purchase, there is no tenant to review at all. The ratio runs on the appraiser’s opinion of market rent, and the lender closes. Whether you then fill the unit with someone who pays on the first or someone who stops paying in March is a question underwriting never asks.
So the asymmetry is this: the lender runs a full identity and sanctions screen on you and your entity, and runs nothing at all on the person who generates the income the loan is priced against. If you want that screen done, you do it.
The four things worth checking, in order of what they actually predict
1. Income, verified against something other than a stated number
The standard is gross monthly income at three times the rent. On a unit renting for 1,600 dollars, you are looking for about 4,800 dollars a month. That threshold is conventional rather than magic, and in a tight market you will see applicants at 2.5 times who pay perfectly for six years.
What matters is the verification, not the multiple. Two recent pay stubs plus a bank statement showing the deposits actually landing is a real check. An offer letter is a promise. A verbal from somebody who answers a cell phone and says they are the applicant’s manager is nothing at all.
For self-employed applicants, ask for two years of returns or twelve months of business bank statements. You are doing a smaller version of what a lender does to a self-employed borrower, and for the same reason.
2. Payment history on housing specifically
A credit report is useful mostly for one thing: whether this person has a pattern of paying obligations on time. A 640 with clean housing history and some medical collections is a better tenant than a 720 who has been chronically late on a car note. Rent rarely appears on a credit file at all, which is why the landlord reference matters more than the score.
Call the prior landlord, and call the one before that. The current landlord has an incentive to give a glowing reference to someone they want gone. The prior landlord has no stake left and will tell you the truth.
3. The eviction search, which is a separate product
Eviction filings do not reliably show up on a credit report. They are county court records, and you either pull a dedicated eviction search or you do not know. Expect to pay 10 to 25 dollars for a multi-county search through a screening service.
Read the result rather than reacting to it. A filing is not a judgment. Plenty of filings are dismissed, settled, or entered during the moratorium years against tenants who then paid everything back. What you are looking for is a pattern: two or three filings across different addresses and different years. One filing from 2021 with a dismissal is noise.
4. Criminal history, carefully and narrowly
This is the part where investors get themselves into trouble. A blanket refusal to rent to anyone with any criminal record has been treated as a fair housing problem, because it produces a disparate impact. If you screen on criminal history at all, screen on a defined, written standard tied to the safety of the property and the other tenants, apply it identically to every applicant, and consider how long ago the conduct occurred.
Write the standard down before you take an application. Then you are applying a policy rather than making a judgment call about a particular person, which is the whole point.
The adverse action notice, which most small landlords skip and should not
Here is the piece almost nobody knows. When you pull a consumer report on an applicant through a screening service and then deny them, charge them a higher rent, or require a larger deposit because of what was in that report, you have taken an adverse action. Federal credit reporting law requires you to tell them.
The notice is short and it has to contain specific things: that adverse action was taken, the name and address and phone number of the consumer reporting agency that supplied the report, a statement that the agency did not make the decision and cannot explain it, notice of the applicant’s right to a free copy of the report within sixty days, and notice of the right to dispute inaccurate information.
You can deliver it in writing, electronically, or orally, though writing is the only version you can later prove you sent. Keep a copy with the application.
Two things make this worth doing properly. The first is that the penalty structure for willful noncompliance is unpleasant and the plaintiff’s bar knows small landlords do not send these. The second is that the notice is genuinely useful to the applicant, who often has no idea there is a decade-old judgment on their file that belongs to somebody with a similar name.
If you deny for a reason that is not in the report, such as insufficient income on documents the applicant handed you directly, the notice requirement does not attach in the same way. In practice, sending one anyway costs you a stamp and removes the argument.
What a bad tenancy does to the ratio, worked all the way through
Take a single family rental. Purchase at 215,000 dollars, 25 percent down, a loan of 161,250 dollars at 7.25 percent on a thirty year amortization. Principal and interest comes to about 1,100 dollars. Taxes 310 dollars a month, insurance 115 dollars a month. Total payment including escrows is roughly 1,525 dollars.
Market rent is 1,850 dollars. Your debt service coverage ratio is 1,850 divided by 1,525, which is 1.21. That closes comfortably at most lenders.
Now place a tenant you did not screen. They pay through month five and stop. You file in month seven, get a hearing in month nine, and get possession in month ten. Then the unit needs paint, two doors, and a carpet replacement.
- Lost rent, months six through ten: 9,250 dollars
- Filing, service, and attorney: 1,400 dollars
- Turnover repairs beyond normal wear: 3,800 dollars
- Vacancy during the turn, six weeks: 2,775 dollars
- Security deposit applied back: minus 1,850 dollars
Net damage is about 15,375 dollars. Against a gross annual rent of 22,200 dollars, you have lost roughly 69 percent of a year’s revenue on one tenant placement. Your real collected rent for that twelve month stretch was about 12,950 dollars, which against a 1,525 dollar payment is an effective ratio of 0.71.
Your lender will never see that number. The loan was underwritten at 1.21 and it stays underwritten at 1.21. You, however, wrote checks out of pocket for most of a year. The full timeline and cost of an eviction is worth reading alongside this, because the months are the expense and most investors underestimate them by half.
Set that against what screening cost. A credit and eviction package runs 35 to 60 dollars, and most jurisdictions let you charge the applicant an application fee that covers it. Two landlord calls take twenty minutes. The entire defense against a 15,000 dollar outcome costs you under 100 dollars and half an hour.
The mechanical parts that keep you out of fair housing trouble
Written criteria, published before you take applications, applied in order received. That is the whole system. Post your income multiple, your credit floor, your eviction standard, and your occupancy limit, and then take applicants in the order they completed the file.
Do not improvise. The moment you make an exception for one applicant and not another, you have created the comparison that a complaint is built on. If you want flexibility, build it into the written policy as a stated alternative, such as accepting a lower income multiple with an additional deposit where state law permits one, and then offer it to everybody who falls in that band.
Be careful with occupancy limits, familial status, and source of income. A refusal to accept housing vouchers is unlawful in a growing number of states and municipalities even where federal law does not require acceptance. Check your specific jurisdiction before you write that into your criteria.
What to do with the tenant you inherit
Buying an occupied rental is a different problem, because the screening already happened and somebody else did it. You do not get to re-screen a sitting tenant with a valid lease. What you get is the estoppel certificate, the payment ledger if the seller keeps one, and the deposit accounting.
Ask for twelve months of payment history in writing. A seller who cannot produce it either has no records or has a reason. If the tenant is on a month to month arrangement with no written lease, you have flexibility you would not otherwise have, and the lender has a different income problem. If they are well below market rent, the lower-of rule will cut your qualifying income, and you should know that before you write the offer rather than after.
One more inherited situation worth checking: whether the lease permits the tenant to sublet the unit. If it does, the person paying rent and the person living there are not the same person, and nobody screened the occupant at all.
Where the rest of the lease documents fit
Screening is the front door of a set of decisions that run together. The security deposit you collect and how you hold it is your only real recovery against a bad outcome, and in most states the amount is capped. Requiring renters insurance in the lease shifts a category of loss off your policy for about 15 dollars a month of the tenant’s money.
Once somebody good is in place, the decision shifts from screening to retention, and what a rent increase at renewal is actually worth against the cost of a turnover usually argues for keeping a paying tenant at slightly under market. The arithmetic there is not close.
If you are not going to do any of this yourself, hire it out. Whether a property manager earns ten percent turns almost entirely on whether they screen well, because that is where the money is won or lost. A manager who fills units fast with weak applicants is more expensive than no manager.
And on a student rental, screening works differently again, since by the bed leases and parent guaranties shift the credit question to someone who is not living there.
Timing it against the loan
On a vacant purchase, the clock between closing and the first rent check is where your reserves get used. The rent-ready standard and the vacancy clock tell you how long that gap usually runs. Start marketing before you close, screen while you finish the turn, and have an approved applicant ready for the day the certificate of occupancy or rental registration clears.
What you should not do is compress screening to shorten that gap. Three extra vacant weeks cost you about 1,400 dollars on an 1,850 dollar unit. A bad placement costs you ten times that. And every one of these properties shows up on the schedule of real estate owned that decides how big your next loan gets, which means a unit sitting in eviction is not just this year’s problem. It is next year’s borrowing capacity.
The short version
Verify income against documents, not statements. Call two prior landlords, not one. Pull a dedicated eviction search, because credit will not show it. Screen criminal history only against a written standard applied to everyone. Send the adverse action notice when you deny on a report. Put the criteria in writing before the first application arrives and then do not deviate from it.
Run your actual numbers through the DSCR deal calculator with a realistic vacancy and collection loss built in rather than a perfect year, and you will see how little room a 1.2 ratio leaves for a tenant who stops paying.
