I bought it last year because I thought the price was pretty good considering it's located in Brookline and gives good cash flow.

Doing this for a few years with honest effort will put alot of extra money in your pocket. 

That usually calms them down, although I have had 1-2 leave over the years (good riddance). 

Property I bought in May of this year has appreciated 15% already.

You missed Parma by 6 7 years.

The property I'm considering investing in is a multifamily facility, ~600 units with 95% occupancy, and the play is to increase value by renovating the units and holding for 4-5 years.

But we still do a Facetime for each property.A lot of "unfinished" turnkeys in bad neighborhoods have been sold over the years, by people who have fled the country. ;-) (Portugalseems to be a popular place to flee to).

Hello,We have been using Buildium for 7 years but have noticed a number of "glitches" lately.

But since J properties generally depreciate over time (not like properties back home which appreciate), the idea of sinking cash into a property that is worth less five years from now is not terribly appealing.Like you say, then the question is what sort of yield can you get, and will it cover the deprication losses?

I was looking to buy a home from him last year but he blasted me in an email for looking him up on @biggerpockets  in this post, so I stopped communication.
