Miami is a great market for house hacking.

Anytime you see a house getting flipped, watch to see who lists it.

Although in Canada it was/is the Ensuite room. and even here on Biggerpockets one lady got on about how she is lobbying in the state of Indiana to have the term Landlord removed from the vernacular and replace with  ( Housing Provider)  the thought being Landlord denotes Lord of the land and superiority over the tenant I guess is the point. 

I've been reading up on 203k loans as a means to acquire a main house and then fix up a garage as an ADU. 5.

A friend of mine wants to buy some land behind his house in southeastern MA.

1. you're right in the new ones from developers don't produce any cashflow. you might want to look at the secondary market to get better yields as the properties are already built and can cashflow right away. also easier to see comparable rents in the same development. check bank repos, distressed sellers and the like. you might also want to get a parking slot for added income as they can be leased out separately. it's also quite difficult to sell without one should you decide down the road. developers usually have an in-house leasing team to handle property management which we use for some of our properties.  

Taking this extra step ensures veterans have the same opportunity as others to compete in a tight housing market.

They don't buy a lot, and even when they or any affordable housing developer buy land, it often can take forever for them to consider the property and then the actual escrow can be long if they are building the capital stack to buy the property. 

Currently getting quotes from contractors to expand and finish the basement in my south philly row house (east passyunk).

While this is in another state, it should translate.I just bought a house in Florida and it has a detached garage that was converted to an efficiency apartment.
