I will edit my analysis to include these 2 factors.

In tight markets, this can even drive up prices, only to have the rate settle back down anyway.  

Stick close to home but maybe a couple hours driving distance.

Offer a service (e.g. you drive and buy the food) while they check properties and run the numbers. 

Then do your own driving for dollars and utilice the things that get to know the market and then determine your income!  

Try not to purchase homes on busy streets unless they have parking in rear or a turn-around drive-way.

Got this one yesterday for my STUDIO honeymoon cabin:2 stars“Feel where this house is all one room no privacy”'Cause, y'know, studios are so known for their multiple rooms...Other complaints in his private remarks included getting lost on the way to the cabin... when I provide explicit directions and clearly state in the check-in email that it's up a private drive that doesn't appear on GPS.  

From there you need to get Realtors or local folks to drive by the property and give their synopsis of it. 

The property is 100% occupied, but I still factor 15% vacancy rate as the Texas standard. 

Of course, if you aren’t offering to pay them their commission, let them know they’ll need to factor their commission into the purchase price.
