It is important that you know your risk tolerance and your objective.

What tolerance does the normal person have for this inconvenience? 

Mistakes will be made as a PM--no one is perfect, but investors are more tolerable when you over communicate.4) Be accessible during the sales process.

A little education and tolerance now will build you a long list of frequent buyers.

I would encourage everyone to read the forum rules.People can disagree on opinion but no personal attacks even made in jest or without malicious intent will be tolerated.

I've told guys that work for me that I will not tolerate this and ALL wires need to be screwed down tight.

The better the contractor, the less tolerance they're going to have for shenanigans.

Free and clear properties are more attractive targets (not only for litigation-happy folks but also - heaven forbid - for divorcing spouses).Consider your risk tolerance, of course, but consider using leverage on all your investment properties - even if you need to eventually keep your LTV around 60% or 50% so you can sleep better at night.

heres my example:$100,000 home = $2,000/month, this you can profit from$1,000,000 home = $20,000/month, these numbers make no sensethe math just doesnt make sense. there has to be another part of the rule. different parameters and tolerance levels based on region. 

Your risk tolerance, liquidity and ability to close quickly will also be critical.
