What it costs at different down payments
On the $1,198,815 project above, at the current 7.4% 30-year rate. Monthly figures are principal and interest only — taxes, insurance and any HOA are on top, and during construction you pay interest on drawn funds instead.

Conforming limits in District of Columbia
Every county in District of Columbia is designated high-cost, with limits from $1,249,125 up to $1,249,125. A median project here needs more than the $832,750 baseline, so whether your loan is conforming depends on which county you build in.
Highest limits in the state
Why it matters: a conforming loan is bought by Fannie Mae or Freddie Mac, which standardises underwriting and pricing. Above the limit you are in jumbo territory — fewer lenders, a larger down payment, and qualification judged on your whole financial picture rather than a standard template.

How a construction loan actually works
The mechanics are consistent across lenders. The terms — rate, draw schedule, contingency rules and fees — are not, and no public source publishes them, so those come from your own quotes.
- 1
Approval and appraisal
The lender underwrites you and the project together, and appraises the house from the plans and specification — a value that does not exist yet. A thin set of drawings or an unusual design makes this harder, which is one reason post-frame and other non-standard builds can be difficult to finance.
- 2
Closing and the first draw
You close on the loan before construction starts. Lenders generally expect the land to be owned outright or bought with the loan, and will want the builder contract and budget attached to the file.
- 3
Draws against progress
Money is released in stages as work completes, with an inspection before each release. You pay interest only on what has been drawn, so the cost of the loan builds gradually through the project rather than all at once.
- 4
Contingency and change orders
The budget is fixed at closing. Changes and overruns generally come out of your pocket rather than the loan, which is why a contingency line that you control matters more here than on a purchase.
- 5
Conversion to a mortgage
A construction-to-permanent loan converts to a standard mortgage once the certificate of occupancy is issued, usually at a rate set near conversion rather than at closing. A standalone construction loan has to be refinanced instead, which means qualifying twice and paying two sets of costs.
What the same money buys existing
The typical existing home in District of Columbia is worth $737,619, against $1,198,815 to build a median-size new one with land — a difference of $461,196 in favour of buying. That gap is also a financing difference: a purchase mortgage is simpler, cheaper to originate and does not carry construction-period interest. Full District of Columbia comparison
District of Columbia construction financing questions
How much do I need to build a house in District of Columbia?
A median-size new build in District of Columbia runs about $1,198,815 all in — $626,980 of construction at $290/sq ft for 2,162 sq ft, plus roughly $571,835 for land at the state's measured land share. At 20% down that is $239,763 of cash and a $959,052 loan, which at today's 7.4% 30-year rate is about $6,640 a month in principal and interest once it converts.
How does a construction loan work?
Money is released in draws as work completes rather than in a lump at closing, with an inspection before each release, and you pay interest only on what has been drawn. A construction-to-permanent loan converts to an ordinary mortgage when the certificate of occupancy is issued; a standalone construction loan has to be refinanced instead, meaning you qualify twice and pay two sets of closing costs. Overruns and change orders generally come out of your pocket, because the budget is fixed at closing.
What is the conforming loan limit in District of Columbia?
Every county in District of Columbia is designated high-cost, with limits from $1,249,125 up to $1,249,125. A median project here needs more than the $832,750 baseline, so whether your loan is conforming depends on which county you build in. A loan above the limit for its county is a jumbo, underwritten outside Fannie Mae and Freddie Mac, which usually means a larger down payment and stricter qualification.

How much down payment do I need for a construction loan?
More than for a purchase, typically. On the $1,198,815 project above, 20% is $239,763 and 25% is $299,704; many construction lenders want the higher end, and land you already own can count toward it. Exact requirements are set by the lender, not by any published rule, so get the number from them before you plan around it.
