Financing Infill and Teardown Lots for Investors: Building on a City Lot in 2026
Some of the best build opportunities are not on the edge of town where the subdivisions go up. They are the empty parcel between two finished houses, or the tired structure on a good street that is worth more gone than standing. Investors who can finance an infill lot or a teardown have a real edge, because most of the competition is chasing the same listed houses while these parcels sit overlooked. The catch is that financing a build on a city lot is a different animal from buying a house, and the loan that funds it has its own rules. This guide walks through how lenders look at infill and teardown deals, how the money comes out, and how to size one before you commit.
Infill and teardown builds are a ground-up product, so if you are new to construction financing start with our overview of ground-up construction loans for investors. This piece narrows in on the lot itself: the vacant infill parcel and the teardown, and what makes each one finance the way it does.
Infill versus teardown: two different starting points
An infill lot is a vacant parcel inside an already-developed area, usually with utilities at the street and neighbors on both sides. You are building one house on one lot in a neighborhood that already exists. A teardown is a parcel that has a structure on it you intend to demolish, where the land plus location is worth more than the aging house. You buy the property, remove the building, and build new.
The reason the distinction matters to a lender is what they are actually lending against at the start. On an infill lot the collateral is land you can build on right away. On a teardown the collateral on day one is a house you are about to destroy, which means the lender is really underwriting the finished value and the land, not the existing structure. Both end in the same place, a new building on a city lot, but the front end of the loan is sized and sequenced differently, and knowing that before you make an offer keeps you from over-promising what the loan will cover.
How the lender sizes the loan
A construction loan on either lot type is quoted against two ceilings, and your loan is the lower of the two. The first is loan-to-cost, a percentage of your total project cost, which is the lot plus the full construction budget plus soft costs. The second is loan-to-completed-value, a percentage of what the finished house will appraise for or sell for. These two caps are the heart of every ground-up loan, and if you have not worked through how they interact, our explainer on loan-to-cost financing is the place to start.
On an infill build in a strong neighborhood the completed value is often generous, because finished comparable sales nearby support a high appraisal, so the loan-to-cost cap tends to be the binding one. On a teardown the math gets sharper, because you are paying real money for a parcel and then spending more to demolish what is on it before a single foot of new structure goes up. Demolition is a cost that adds nothing visible to the collateral, so it has to fit inside your budget and your equity rather than relying on the building to support it. A lender wants to see that you have accounted for it.
The demolition piece on a teardown
Demolition is the line item that surprises first-time teardown builders. Pulling a house down is not just a machine and a dumpster. There can be utility disconnects, permits, asbestos or lead abatement on an older home, and disposal fees, and the total can run from a few thousand dollars on a simple frame structure to well into five figures on a larger or contaminated one. None of that spend shows up as value in the ground, so you are carrying it until the new build catches up.
The practical move is to treat demolition as its own early stage in your budget and your draw schedule, funded right after closing, with the rest of the build sequenced behind it. Get firm demolition and abatement quotes before you close, not after, because a demolition overrun on a thin teardown can wipe out the spread you were counting on. This is the same discipline that protects a flip, where a careful rehab budget is what separates a real margin from a wishful one.
How the money comes out
Construction money on an infill or teardown build is released in draws, the same as any ground-up loan. The lot or property is funded at closing against the loan-to-cost cap, your equity goes in alongside it, and then the construction budget is metered out in stages as the work gets done and inspected. You front each stage and the lender reimburses after an inspection confirms the work, so you are always carrying some completed-but-unfunded work in between draws. If the draw mechanics are new to you, our walkthrough of the construction loan draw process lays out the sequence step by step, and the discipline is the same one that makes a fix and flip draw schedule run smoothly.
On a teardown the first construction draw after closing is usually the demolition and site prep, which clears the lot and gets you to the same starting line an infill builder begins from. From foundation forward the two build types run the same draw schedule.
Real numbers on an infill build
Concrete math makes the leverage clear. Say you find an infill lot for ninety thousand dollars in a neighborhood where finished comparable houses sell around four hundred thousand dollars. Your construction budget plus soft costs is two hundred forty thousand dollars, so your total project cost is three hundred thirty thousand dollars. Run it against both caps. At eighty-five percent loan-to-cost your loan would be about two hundred eighty thousand dollars. At seventy percent of the four hundred thousand dollar completed value the cap is two hundred eighty thousand dollars as well. The two ceilings land in roughly the same place, so your loan is about two hundred eighty thousand dollars and your equity is about fifty thousand dollars plus closing costs.
Now run a teardown to the same finished house. The parcel with the old structure costs one hundred forty thousand dollars because the location commands it, demolition and abatement run twenty thousand dollars, and the build is the same two hundred forty thousand dollars, for a total project cost of four hundred thousand dollars against that same four hundred thousand dollar completed value. The loan-to-completed-value cap at seventy percent still holds the loan near two hundred eighty thousand dollars, but now your total cost is four hundred thousand dollars, so your required equity jumps to about one hundred twenty thousand dollars. Same finished house, same loan, far more cash in. That is the teardown tradeoff: you pay for location up front, and the loan does not stretch to cover it because the loan is anchored to the finished value, not to what you paid for the dirt.
The interest reserve and your carry
Most construction loans set aside an interest reserve at closing so you are not writing an interest check every month while the lot earns nothing. The reserve draws down as interest accrues, and because your balance grows with every construction draw, your monthly interest grows with it. Treat the reserve the way you would an interest reserve on a fix and flip loan: it is borrowed money you pay interest on, and every month you run over schedule burns more of it. On a teardown the demolition phase is dead time as far as the building is concerned, so it adds carry before any value goes up. Build that into your timeline and your reserve, not your optimism.
Planning the exit before you build
Every ground-up loan is short term, so the exit is part of the plan from the start. If you are building to sell, the sale proceeds repay the construction loan, the same as a spec build, which we cover in our guide to spec home financing. If you are building to hold, or the sale market softens, you refinance the finished house into a longer-term loan. When the rent supports the payment, a DSCR rental loan takes out the construction loan cleanly. Run the finished value and the rent before you build so you finish the house to the standard your exit actually needs.
