Overall both the FHA 203K and the Fannie Mae HomeStyle are great programs. IMO one is not necessarily better than the other. Its really more about what is the best fit for the individual (credit score, DTI, down payment, etc.). One key thing that no one thinks about with FHA loans (all FHA loans, not just 203Ks) is the self-sufficiency rule, which applies to 3 and 4 family homes. In order to pass the self-sufficiency test, you'll need to prove that 75% of the rental income you're likely to receive (including the unit you would occupy) will exceed the full monthly mortgage payment. That means calculating both the monthly rental income and the monthly mortgage payments.
In order to figure out the numbers, you’ll first need to get an appraiser to value the rental potential of the property at market rates. In other words, the appraiser will tell you how much rent you can expect to charge at the going rate (not at historical or actual rates).
Even more critical than the appraisal, however, is the loan calculation. In fact, correctly calculating the cost of the loan is the single most important step in the qualification process, determining how much the FHA will be willing to cover and, therefore, how much you will be able to finance.
Included in that monthly mortgage calculation are the following costs:
- Principal
- Interest
- Taxes
- Mortgage insurance
- Homeowner’s insurance
At the end of the day, your loan officer should be able to crunch these numbers properly to ensure you do not find yourself in a bad situation. You will be amazed at how many FHA experts do not know about this rule and it comes to light AFTER the contract has been written, monies paid for inspections and appraisal completed.
