The 203k Rehabilitation Program is the FHA/HUD main loan program providing home repair assistance for single-family dwellings.
There are 2 different loans programs based on loans amounts:
Renovating your current home: If you already own a home and want to finance improvements, you can refinance your existing mortgage with a 203(k) loan to free up cash for renovations.
Buying a fixer-upper: If you find a house that needs repairs in order to be livable or that you want to upgrade, you can use a 203(k) loan to cover both the purchase price and the cost of renovations.
Just one mortgage: You apply with a lender for one FHA-insured mortgage that covers both the purchase price of the home and the cost of renovations.
Split loan amount: The loan amount is divided into two parts: one for the mortgage balance (or purchase price for a home purchase) and one specifically for the renovation project.
Escrow account: The funds for the renovation project are held in a special escrow account. This account ensures the money is used for approved improvements and helps manage the project flow.
Staged releases: The money is released to the contractor in stages as the work is completed. A qualified inspector must sign off on each stage of the renovation before the next tranche of funds is released from escrow. This protects both the borrower and the lender.
