The sale would include 2 duplexes, all of which are being rented.

I am currently in the final part of a "new" building duplex in Houston.

I actually think certain types can be decent investments IF you do the homework and read the docs and know what you're buying into.I personally avoid high rises (too much cap ex and high maintenance costs mean poor return), poorly maintained buildings with lots of deferred maintenance, avoid non-warrantable buildings or complexes (hard to finance), I prefer townhouses or 4plex style condos with only one common wall and nobody above or below, that limits neighbor and tenant drama. 

My cost to the tenants is $50 per wall that they'd like painted, and I tell them my painters need to do it for liability reasons + to protect them from getting charged to paint it back to it's original color at the end of their tenancy.

Another option is to look into a duplex or a tri-plex or maybe even a quad-plex.

So it looks like since its duplex the bank I did my last loan with (second home loan that we turned into an airbnb short term rental in Ocean City) said we had to do a investment loan and put down 25%.
