This is like saying you want to spend $5500 on a vehicle. 

What finance vehicles or methods are you using?

My houses are just a vehicle for making money, no more no less, and the more landlords that don't rent to anyone who has a pet, the more rare and desirable my places become. 

The only vehicles which cannot lose face value are CD's, online FDIC savings accounts (Ally, Discover, etc) and TIPS purchased from the US Treasury Directly (TreasuryDirect.gov).

One thing to remember, is even if you find the best property management company in the world, you will still need to be involved in the asset management..it is not a 100% passive vehicle as many people think.

Current living situation will tell you if you are getting consolidating households and number of vehicles is something I like to ask because it uncovers multiple singles and hoarders in my area.  

Do you have a driveway that will be used by two vehicles or is it a multi-family parking lot that will be used by 20 vehicles and guests?

Will you keep a vehicle down there? 

Pulling in a 12% return on an initial investment in a rental property can't be compared to an investment account that is reducing your tax base, reinvesting dividends and most importantly- compounding.I am not knocking one over the other, I have and love both, but they are 2 vastly different vehicles.

You can have underground vehicle sensors which work great.5.
