FHA loan qualifications and income sources

[Jim Lou]

So I'm really confused about how to qualify for FHA financing. Everything is so vague and obscure when it comes to mortgages.

Here's my question:

It's my understanding the debt limit is 46.5% on the front end and 55% on the back. Does the income they use come from the prior years tax return or the current year? 

I purchased 2 properties in September of last year. I didn't make much in rent and had a lot of deductions for repairs and such. My income last year was 70,000 with and agi of 52000 after losses. 

This year I got a raise and I also will have significant rental income. 

My income from my job will be about 91,000 this year. I have more than 80% equity in my 2 properties so it's my understanding the FHA counts 75% of your stated lease towards income. So my second question is, what is my max payment I can qualify for?

Property 1 purchased for 180k, appraised for 300k. Rent roll is $2745/mo

Property 2 purchased for 215k, appraised 300k. Rents $3200/mo

So my monthly debt payments are 

Student loans 600/mo

Car payment 361/mo

Mortgage 1 $1530

Mortgage 2 $1350

What will I qualify for roughly???? Thanks guys!!!
