I love the cash flow,  easy maintenance and that I even bought one using a credit card once for a down payment! 

Lay your cards on the table as to what type of property you are acquiring and what your plans are and they should educate you on the type of coverage they have to offer. 

@Robert Kirkley lots of ways to use cash back credit cards in your favor.

Multiple bank accounts mean multiple cards to carry around.

A transaction is a transaction.. and you have to play the cards that are dealt to you in each market.. safer to do it at home then try to rehab half way across the country. and we know that retail sales in many other markets can take a long time to move and usually for a lot less than what you think or your ARV valuations come in at.   

To note we've paid all the rest of our outstanding debt including cars and now just have a credit card balance that we pay.

Without increasing asset prices (nominal), or worse yet, decreasing asset prices, the house of cards comes crashing down.  

Give the neighbors your card and invite them to call you directly ("don't waste your time on these people, call me"). 

Others will disagree but I am not a fan of pulling the lawyer card w/ college students unless it is 1,000% necessary.

Cashflow is my number one goal but to gauge appreciation potential/rent growth I look at:Location (market) - Census trends, average price to rent ratios, employment rates, landlord/tenant laws, tax rates (1% in CO is very different from 4.3% in upstate NY)Location (submarket) - Schools, crime, walkability, "path of progress" trends, distance to downtown/jobs, public transportation, commercial development
