Whoever told you that likely is trying to charge you a fee for “trade accounts” lines of credit......Home Depot, Lowe’s, staples, grainger, etc., Not a Cash line of credit.

Here is what I generally use in Memphis for my ratings:A+  no cashflow whatsoever if you bought here, good appreciation, great schools, larger houses, beautiful homesA great neighborhood well kept mostly all homeowners, more likelyhood of appreciation, not as great of cashflowB decent area but some homes are not perfect, quite a bit of renters but still homeowners, decent cashflow, decent/some appreciationC Very few homeowners if not any, more run down houses, good cashflow, very little appreciation, D&F  Warzone, dont event want to get our of your car, lots of boarded up houses, cashflow looks amazing on paper 2-3% rule "on paper" ARV < $45k

Pay attention to conversations where you uncover someone is a contractor or works in a specialized trade.

Add to that they are normally more well versed in the trade and can answer questions better. 

Lots of things can happen that we all have no control over.How does the trade war with China turn out?

They learned how to weld or do pipe fitting in high school or trade school. 

saw that in Vegas as well.this was mainly in areas were new construction was HOT and when it stopped it came to a screeching halt and all those sub trades found themselves without a job.. and simply left. my clients bought multiple MF from me in the Portland Vancouver market.. they lost some value but did not go vacant. these were lawyers and very professional types from SF bay area.. it was a disaster for them multiple foreclosures on their fico's.. it stung bad.Not saying that will happen in the future as I am gung ho new construction personally.. but it did happen.

The reality is, the nephew/tenant has no incentive to cooperate in this scenario whatsoever since he's living there for free and it's not in his best interest if the house sells. 

I would trade them in and get two reliable, fuel-efficient cars like a Honda Civic.2.

We are looking at possibly new young tenants that have no credit whatsoever.
