Just have everything functional and that's it!

This past year I have helped clients with cash-flowing short term rental properties (in Boulder County where it’s still legal, not City of Boulder), condos, and just helped a client pick up a SFH near the university with a bonus studio apartment built off the back that functions like a duplex and has initial cash flow.

@Eli Shicker there are also free options out there that offer most if not all of the functionality you’d need.

This is also a function of size, i.e.

We are nearing the end of DIY renovations ( it looks pretty awesome though and functions).

So you can imagine how inefficient the search function is for me right now.

Then for rentals, you would want some durability to go with affordability, so look up,  via the search function, the threads on how to harden a rental for ideas in that aspect. 

The inspection may allow you to spot major issues (like a hole in a tank), but functional testing can likely only occur when folks are living in the house.

It seems like the 3/1/1 layout is functionally obsolete, and yet very common in the Baltimore area.A lot of the 1/2 baths are in basements.

I would not add any shutters because there's nowhere to add them where they will look coherent or functional.
