These properties will generally command a premium to a property that is either not rented out or has deferred maintenance.  

I signed up online for water service, but was denied because apparently I need a master meter, which requires almost as much documentation as purchasing the property itself!

Only expenses are lawn and typical maintenance. 

This allows me to do a 1031 exchange and get into newer properties with better tax advantages (once I have used up most of the depreciation from the previous rental), and it allows me to never deal with deferred maintenance issues that increase my cost of ownership.

Hi @Carlos Martinez welcome to BP and thank you for your service. 

I recently considered a service that basically does what you mention specifically as "corporate housing" with companies, but never went further into it as I ended up renting the unit out to some normal folks.

I normally have them sign the Information About Brokerage Services if we meet up and ALWAYS have them sign the IABS and a non representation agreement if we agree on a price and I get the house under contract.

More than a half century of deferred maintenance doesn't recover overnight.I think there's still a ton of upside, but it's going to be the hardest dollar you can make. 

My goal is to pay a fair price for good service and not be taken advantage of.

I am here to extent my services as a Buyer's Agent, Listing Agent, Investor's Agent, and Property Manager to anyone who need help or even just advice.
