(not trying to be a jerk, just pointing out what should be obvious)Thanks Michael,  yeah I approved just some painting same day but I think my problem lies in they aren't even diagnosing the potential work until tenant leaves leaving a gap in time. 

Once my wife was diagnosed with breast cancer that difference was tangible and real.But the biggest reason I did it?

While we were working on the first unit, my husband was diagnosed with cancer and we put the project on hold for his treatment.

I might diagnose whether it is a people or property problem first. 

That is where the doctor and testing hopefully can pin point the cause.In the case of a building, a structural engineer may be able to help you out if you or your inspector suspect that there may be a structural defect.I would suggest that you have an experienced investor friendly structural engineer on your team to help you diagnose possible structural defects that you may suspect.This may sound like a lot but from my experience, most single and multi-family residences do not exhibit symptoms of structural distress.If you do find a property that you are interested in and it appears to have some hidden defects, this may be a great opportunity to negotiate a good deal.

Louis, MO and while I don't own any properties nor have I flipped/renovated/rehabbed any homes (at least for profit, I have helped friends) I am INCREDIBLY passionate about REI and getting into the house flipping (I'd ABSOLUTELY LOVE to focus on historic homes).When I was 20 I was diagnosed with an auto-immune disease that I'll live with for the rest of my life.

Chris, I think I would do a little fact finding (and it seems you have) and even think about thanking the neighbor for the input and letting them know you will be looking into it...I like to try and diagnose if it is an issue conflict, like really a noise problems, or a personal conflict, like the two don't like each other..

If cash flow is lower than $300 u will feel stress as every little fix ( if u are not up to doing the fixes urself) would cost at least $75( cost to have someone diagnose the problem).

Thankfully we were in the Palo Alto School system this was diagnosed by the Teachers they had special class's and teachers to handle it and now he is fine at 35 Y Old.. although never going to be a speed reader.. but my brother had the same thing in the 60's and early 70s and he had a terrible time in school.. you got shuttle into the special class they never learned how to read and many end up in trouble in society or get labeled like you are labeling them.  

The more you drive for dollars, the better you will get at diagnosing if somebody may be motivated.
