Hey SuzanneThe reason for the floor plan could be to determine square footage percentage of residential units vs commercial space.  

My main question is, do property managers typically charge a higher percentage on units that have lower rents?

Therefore, most underwriters take the loss to lease percentage of the gross potential rents number and apply that percentage to the pro forma projections or assume they can operate the property better by leasing units strategically by having leases expire in hotter (temperature and demand) months, thus applying a lower percentage of GPR loss to lease (typically 2% to 4%).

If so, what percentage do you use to screen deals? 

I still plan on taking out a percentage for repairs, capex, vacancy, and management.

I was under the impression it was the Nursing Home restricting that percentage, but I'm not certain.

However, you may be able to work out a different percentage (including nothing down) with your lender.The Refinance step still is applicable whether you have a Private/Hard Money Loan or paid all cash for the acquisition.  

Small percentage of loans actually go to foreclosure.

Over the past five years, owners of starter homes have experienced a 44.4 percent growth in equity — 17.8 percentage points more than owners of luxury homes (26.6 percent)."

I wouldn't look at expenses per door, expenses as a percentage of gross potential profit.Per door is mainly acq cost and rent...
