You don't want to start a relationship to learn about storage units and then find out they only invest in single-family homes.3.

You could ask your accountant about options for bonus depreciation or possibly updating the properties in order to receive depreciation deductions or write-offs for repairs, maintenance, etc.

I came across this case nearly a decade ago and in that time I’ve yet to find a single RE attorney, broker, agent or investor that has ever heard of it.

They will set up their own account and upon move-out do a factory reset for the next tenant!  

Currently own my primary residence and 2 investment properties are a beach condo (short term) and single family home (long term rental).The problem is I run a successful business and have no time to do the research in new markets, deal flow, upgrades, making sure cashflow, property management, etc.I am also not a real estate professional.

Does it matter if I keep the rents in my personal accounts?

There was not a single house that did not have technical issues beyond just repairing.  

On expensive apartment like these, if rent is too high, they would just rent a single family. lol.too much work for nothing.

show your accountant your payment to them. 

While these are all great to have, its like trying to find the perfect spouse, you can keep turning over every rock to look, but at some point you will need to compromise and then realize your money was sitting in an account doing nothing for years because you were looking for the perfect deal.
