I always use Pinpoint Home Inspections.

The tenants all sign a list of rules when they move in but this is one rule that's hard to enforce considering I can't pinpoint the unit (4 unit building).

It’s an increase from their previous lease, but clearly identifies and pinpoints aspects of the lease that they are breaking.

(not sure exact date): Public adjuster goes to house to inspect damageJuly 11: I sign contract with public adjuster to take on caseFrom this point on, things get hard to pinpoint.  

The sub-markets of any city are where you are going to better pinpoint cashflow v appreciation although the greater metro market indicators are still important.For example, there are neighborhoods in columbus (the higher appreciation city, typically) that will have little or no appreciation and just straight cashflow just like there are neighborhoods in cleveland (the lower appreciation city, typically) that have great appreciation potential because of sub-market trends.  

@Adam LaceyI believe anywhere in Greenville or Spartanburg Counties would be good.Values are going up everywhere since it’s the same economic engine.Hard to pinpoint specific areas - the better areas for now are of course more expensive.Each deal is different - it comes down to the numbers.But if you can find developable land anywhere here, it will work well.For my own investments, I look all over these two counties.

Currently live in Fresno, CA, but want to find a great location to pinpoint, analyze as many deals in one market and get a deal.  

I know MA is a smaller state, but you need to pinpoint your location in terms of where you live and where you want to invest and find local experts, at least for the attorney.

@Tom Ott Thanks for pin pointing the type of area we should invest in - it definitely helps to lockdown the type of area you should invest in.
