So if you check property records don't completely dismiss someone as being a liar if the property record and their reference don't match up.

In terms of tenant screening, it is always a good idea to know what you're getting yourself into; definitely cover the basics (ie. employment verification is always a smart step, so you can gain some sense for whether or not this applicant's self-reported income matches actual employment records).

You just need a good match.

I would like to have all genius inverters thoughts on :- 1) Which states and city’s matches the positive numbers for investors to make good returns and good cash flow by renting ?

A manual app to weed out the wrong choices, and then you could decide to pay or charge the prospects you feel are a match...

Well your best bet honestly is to scale higher or lower and play with the numbers a bit of the comp properties to the subject property so that they match.

I sugges you begin to understand your market: identify the city & sub-city you would like to invest in, do all your homework on the area, make a trip and meet everyone that’s worth your time, take a map and highlight the good and bad areas, identify a realtor that you believe is the best match for your needs and analyze as many deals as you can along the way. 

Make sure your material cost matches your receipts.
