Buildium is a solid product and one of the cheapest "professional" systems out there.What I recommend is you take the time to research the most popular options available.

I'll let you connect those dots.To be honest, there would have to be a sea change in regulations for me to spend another of my hard-earned investment dollars in NY real estate, and I can tell you my sentiment is extremely popular with other landlords in the state. 

We’re also popular with SoCal investors, as it’s a relatively short drive across the desert to get here when needed.

@Mark Fries have you looked into areas like Bermuda or the Cayman Islands for setting up a captive they are some of the more popular locations.

Double closings are extremely popular here!

Before I thought finding PM would never be an issue and folks would be excited to get a new client but forgot that in a low income C neighborhood far from the city PMs aren't that popular and people aren't that motivated either to get ahead or something.

Most popular units are 10x10 and down so I think you will have a hard time renting them if you are competing with other storage in the area.You should just build storage if that’s what you want to get into.

In no particular order I have listed some of the most popular markets for out of state and out of country investorsCleveland, OhioDayton, OhioToledo, OhioYoungstown, OhioCincinnati, OhioMemphis, TennesseeBirmingham, AlabamaKansas City, MissouriSaint Louis, MissouriIndianapolis, IndianaDetroit, MichiganErie, PennsylvaniaLouisville, KentuckyMilwaukee, WisconsinJackson, MississippiEach of these markets is popular with turnkey investors because of the low barrier to entry, high rental demand & high rent to price ratio.

I think if BiggerPockets were to have a forum interface similar to popular sites like Reddit, users could have a much deeper interaction and experience with the rest of the BiggerPockets community. 

The key is using several sources and matching them, hence i love using the complaint, defendants, property appraiser and tax collector site (to name the most popular) and THEN do your official records search and compare the results, this way it will minimize the chance of error.
