Question regarding rent used in FHA loan qualification?

[Tyler L.]

So, I’m a little confused on one aspect of FHA income qualification. As I understand it, the debt-to-income ratios on the mortgage can be no more than 31%. However, for house hacking, lenders are allowed to count 75% of rental income towards the loan. Let’s say my income is $500 a month short of qualifying. If my rental income is $1,000 a month, lenders are allowed to consider an extra $750. My question is, do they count the entire $750, or just 31%, $232.50. If it’s the former, I would qualify under the FHA loans. If it’s the latter, I would still be $267.50 a month short? Which is it? Thanks in advance?
