HiI am a remote landlord and have a property manager who goes out and views potential deals and gives me insight on the deal and area etc.What is the usual compensation for this work?

If it matters, these would be very high end rentals with potentially very high maintenance guests.My question is: how would you go about structuring this type of partnership and what would be fair compensation?

That might satisfy the neighbor and keep things as they are for your Mom.It doesn't seem reasonable for the neighbor to take no action and no compensation while your Mom starts talking about adverse possession and taking the land. 

Also if in your price range is mostly cash buyers or most use finance instead.There is a HASSLE FACTOR that sellers often do not compensate for.

Assuming they will be compensated - why not switch to a 3rd party manager? 

However, you can compensate for this by buying with a deep enough discount to account for the extra time and money.

You have a negative cashflow that you can compensate with OOS flows.

Many people use an inspection report to get price reductions to compensate for necessary (either in reality or in buyer's mind) repairs. 

Also another poster said to diy, your supposed to have a epa certification to work with refrigeratant and air conditioning installation equipment is expensive to.As to why a HVAC contractor is expensive is because they have a business to run, employees, workers compensation insurance, general liability insurance, shop expenses, trucks etc.

Would I have to build the compensation into the amount of rent due or could I actually contract it as a free service he provides?
