It makes sense to run the numbers, but will depend on the appraisal. 

I have the applicant go to website and fill out online application form for pre-qualification3.

Most lenders won't require an application fee and should be able to clearly lay out their financing costs, cash to close, and projected profitability for you.I hope this helps.

EVERY applicant is "qualified"!

In some areas, I find that the information is exaggerated (applicant lied) to make their application look betterHere's how I use them:  A lot of times, the applicant will self report information that disqualifies them. 

It's worth comparing terms between your current lender and others to see who offers the best deal in terms of rates and fees.Purchasing a Property: Whether you purchase through regular listings, an agent, or an auction depends on your risk tolerance and expertise.

Most bankers can run live pricing to help you make a final decision without having to have your credit pulled several times or fill out a dozen applications and submit docs!

Mortgage lenders will qualify you for a higher purchase amount for multis than they would on a single, because they will count the rent you will be making on the other units as additional qualifying income for your loan application.

After communicating with a prospective resident (Google Voice #, usually by text), with just a name, telephone number and email, the applicant can pay $55 to provide us with a background, eviction and credit check.

Sub to is just very risky for the seller as denoted in this thread.. for you the buyer very little risk unless like Ken mentions you start to fib on applications etc.
