I'd have to ask my wife who handles the accounting etc about the fee question. 30 to 45min a month for 62 properties Not bad.

RM is plenty robust to handle the items you mentioned.  

So, if deadline not met, we will send our people to handle.4) Vacant properties are easier to deal with, but we still require:- Owner must sign a Hold Harmless to indemnify us against any potential lawsuits relating to the work their contractor is doing and add us to contractor's insurance.--- Another lawsuit from a prospective tenant that slipped during a showing and when they grabbed the handrail, installed by owner's contractor, it collapsed and person injured.- Since we're not really in full control of the property, the Hold Harmless also indemnifies us against anything that goes missing at the property and squatters.We get asked/told to do all kinds of crazy stuff by owners, who either don't care what happens to us or haven't really thought everything through.Hope this addresses your question.

Some used more creative ways to handle the needs but it is still a capital call and dilutes the return (if anything left). 

From all parties it was not handled right.

Start by talking to a cross-border CPA and attorney to handle taxes and legal structures properly.

Strategic timing matters, especially with multi-state portfolios.Real Example:Investment property sale in 2019Federal noticed unreported gainTwo states involvedTimed response to fall after state deadlinesResult: Only federal adjustment appliedInvestors: What's been your experience handling tax notices across multiple states?

And always have reserves to handle any unexpected issues.

I handle dispositions and tech; my business partner is more experienced with exit strategies and the finer points of investment.Hope this helps!
