Maintenance fees and other costs have been very low as well. 

One route you can go is get high level familiarity with what you want.

You have everything from low end inner city properties to rural properties and a ton of small towns in between.

This is the most basic level of protection and it is not very effective, but it is still better than nothing.

If it gets 3 hits in 10 hours, it's too low.

Not everybody is cutout for sales, and its a very low barrier for entry. 

Good Sponsors should have a portfolio of properties in different regions, and usually select properties rated Class-A—high quality, newer buildings with top amenities and low vacancy rates.    

You'll have a "base rate", usually based on LTV and credit score on a grid, and then you'll have "loan level pricing adjustments" (LLPAs) that will adjust that.

Mostly I would highlight what is most important to you and how a CPA will take your portfolio to the next level. 

@Baahir Starkey the easy days of low rates allowing a beginning investor to pick a property on the MLS and have it cashflow are over for now.Now, investors have to do lot of research and pursue motivated sellers, willing to take less than their property is worth.
