To get a commercial investment property loan, qualification will not be based on dollars of cash flow, but rather on DSCR (Debt Service Coverage Ratio).

Providing that the loan is assumable (you will see this in the loan documentation), you will need to meet the exact same qualifications as if you were getting your own loan. 

My qualifications are that I've been a resident manager for mid-sized, commercial multifamily properties for a long time- but didn't deal with the finance side of things- just rent collections, day-to-day maintenance, rent collection, showing vacancies, signing leases, etc. 

You can start this process by simply calling the major banks and asking the terms of their loan programs and what their qualification requirements are.

That way there is no preferential treatment accusations, hurt feelings, etc.The first person to turn in their application and application fee gets screened first, if they meet my qualifications they get first opportunity to put their deposit down for the property.

The previous owner didn't really have many qualifications to get it, just first month's rent and the security deposit. 

We have a minimum income requirement to qualify for this unit (3 times monthly rent); based on your email, it appears you meet those qualifications.

My question is, I know flippers take on properties that are 75% of the ARV (or better) but, what are teardown/new build investors qualifications for max offer? 

Should the property be transferred to my personal name for loan qualification? 

The lender who allows it just asks for your qualifications (licenses, insurance, references, etc).
