This takes a little more work, but it's the fairest and reduces the likelihood of tenants that squander utilities.If you choose #2 or #3, there are considerations:Start with an average.

Really learn how to be an operator.

My initial reaction is that given today's higher interest rates I don't think $100k income will support an 800k loan because the loan payment on an 800k loan (30 Year Am and 7% interest)  is about $5,000 - $5,500 and your income is about $8,300 per month.

Also if the property is zoned such that commercial can be there, you've got more options for an eventual redevelopment in my mind.
