In this case a suggest you hire a public adjuster.  

That way, if a private individual offers you an 8% Adjustable rate loan with 5% down, is that a fair deal?  

The 50% rule tells us that $450 of that $900 will go to expenses, not to include the mortgage, which for this I will just use zillow mortgage calculator with the APR adjusted to 5%,    $900 (Income) - $450 (Expenses) = $450 Cash Flow$450x12=  5,400 (Total Annual Cash Flow)$5,400 / $50,000 (Total Investment) = .108 or 10.8% COCROIIf you purchased that same house using a mortgage with 20% down ($10,000) and a 5% APR then your mortgage payments would be roughly $215/mo (P&I) according to zillow mortgage calculator and the numbers would look like this:MORTGAGED PROPERTY$900 (Income) - $450 (Expenses) - $215 (Mortgage P&I) = $235 Cash Flow$235x12 = $2,820 (Total Annual Cash Flow)$2,820 / $10,000 (Total Investment) = .282 or 28.2% COCROIIn this example, it just makes more since to leverage a mortgage in my opinion.Good luck to you, Happy Investing!

(Ok, maybe I beat him up on the cash offer a little but, as they say "cash is fast and speed is expensive.") 

Most building departments are happy to have you come in beforehand to get up to speed on what is required.

I am spending a lot of time rethinking and adjusting my strategy these days - what I have been doing very successfull for the last 8 years is comming to an end it's time to adjust to a new normal. 

Granted, it is based on fact (like market sales data), but there's alot of adjustments etc.
