You'll want to have an idea of how you handle utilities, and I've heard of the owner covering a weekly house cleaning to keep the peace sort of thing.  

And yeah I am not opposed to the 80% ltv, just figured get the most I can possible to utilize it as best possible with cash reserves left over.

We pay about $1700 for mortgage, insurance, utilities ect.  

Otherwise, they will trash the property, not pay their portion of rent or utilities, and then move on to the next property.

However, as a primary, it depends on the property and how you utilize it. 

In my estimation (local utility costs vary as well as temperature) it is about $400 per month on average. 

Meanwhile these same service providers don't explain the legal process which ties into how the insurance coverage truly works let alone explain how to utilize additional insured status, indemnification clauses amongst many other tools at your disposal  because that is not a profitable business for these service providers to be in.

You will not find a lender who will go below $75,000 on an individual asset if your property appraises for anything less than let’s say 96,000, you’re going to have to utilize what is called a blanket loan.

The properties themselves are often different, maintenance costs are different, purchase prices are different, utility costs are different, etc.
