Buy a nice 4+ bedroom home.

Greater Grand Crossing has some nice pockets.

If you live there 2 years or more before selling you will be exempt from tax on the 1st $250k in profit which is a nice bonus. 

They plant flowers, keep the yard nice, and I really enjoy them.

I actually purchased a SF house with a two story detached garage in a nice area of brockton.

Safe rent after rehab is $900 per month, maybe higher if I get lucky and/or rehab it to a very nice condition.  

We got out of condo conversions couldn't really sell any of them and transitioned to ground up development of single family homes and three story walkup triplexes on a build to rent model which is much easier for us to manage and our exit isn't a sale it's just a refinance. 

It'd be nice if I could receive help or tips from anyone (new or experienced).

I focus on mid-grade quality items that are durable and pleasant to use yet not so nice that people are tempted to swipe them and are then expensive to replace.

I've had a long career in community development and have a lot of bank contacts that would likely be interested in investing, but I'd need to prove the concept first with an initial fund (there are also a lot of other community development tools that could be leveraged to maximize and scale this).
