Economies of scale which leads to lower cost per unit for almost everything (maintenance & repairs, capex, property management, etc)Little income improvements through more efficient management leads to HUGE increase in equity.You have on-site management and maintenance since the property can afford it - so it becomes more passive (notice I didn't say totally passive because it's not)Now they are harder to sell - but that also makes them easier to buy specially when you have a motivated seller on the other end.

What is the best energy efficient dehumidifier to buy for one of my rental properties?

I dont know anywhere, other than Trenton and Camden, where you can buy a turnkey rental in NJ for $100k.Taxes are a big factor.

That’s very streamlined and efficient if the parties work together.  

:P I write it off and move on dot com without whining about it, but I still prefer to be efficient with my time when given the choice/option to do so.

This would protect each asset and keep the books organized most efficiently at the operating company. and a tax return would not be necessary for each property in the SMLLC. 

Pace however is a different factor.

Making 2 efficiencies on 1st floor.

Are there universities, hospitals, large factories near by that you could advertise your units to.

At almost 1,100 feet, I wouldn't rule it out.The best way to determine the annoyance factor is to go to the site and listen from both inside and outside.
