In my experience, PMLs finance all types of deals SFH, residential multifamily up to commercial multifamily. 

The bank asked a million more questions than I get asked when applying for commercial loans but it was never really in doubt that I would get the conventional 30 year loan that I wanted on my primary.

The ability to generate more income for simply the cost of a building is another huge cost saving over buying an expensive commercial lot and developing it.

Quote from @Blake Grzybowski: I am a wholesaler in Michigan and would like to start reaching out to potential sellers who are Maybe foreclosuresdaily.com, maybe see if any of your title company partners has access to titlepro software for leads. 

Do I give up access to transportation, restaurants, cultural activities, doctors, emergency medical care, religious and business activities, vet care and maybe more, to live in the country on my ranch or on the beach in a beautiful country, or do I keep access to all those things and live in the city? 

@Treza Edwards, your lender will often mandate specific inspections to lend on a commercial property.  

It will take approximately two hours, and I need access to every space, including the attic and crawl space.

This is what is pushing up rental demand for small MF properties that having lower rents, fees, or total move in costs compared to other larger commercial apartment complexes.

Commercial?

Some lenders do have minimum credit scores to access these loan types, but it is the exact same qualifications for income and assets as non renovation loans.
