Front-End DTI Ratio Questions

[Account Closed]

Hello all,

I'm planning on making my first home purchase soon (within the next 30-60 days if all goes well).

I am planning on house-hacking - I have some friends willing to live in with me at the house I buy and they are willing to pay me rent. 

Since I will have roommates paying down my mortgage, is it somehow possible to factor this into the front-end DTI ratio? Has anyone seen this to be the case? Of course, I feel that if this gets factored in, I can get approved for a higher amount because less of my income will be going to the mortgage expense (my roommates are essentially paying my mortgage).

Thanks!
