The minimum requirement for any 203(K) rehab is $5000. If a feasability study has detemined that the project will cost a minimum of $5000, then additional costs can be added. FHA handbook 4240.4 section 1.7 states that when basic improvements are involved, the following costs can be included in addition to the minimum $5,000 requirement for the existing structure:
- Construction or rehabilitation of a detached garage or an
attached unit(s) to the existing dwelling (if allowed by the
local zoning ordinances).
- New cooking ranges, refrigerators and other appurtenances
It does not give a limit as to how much you can spend on appliances, they can not be used appliances and they have to meet the most modern energy usage guidelines.
It is my opinion that you do not need another program for buying appliances, you can do it all under the 203(K) loan.
