If not, you can always increase the rent to market value, but my guess is it being California, there are limits to rent increases.There are rent caps but they do not apply to single family homes owned by individuals (not LLCs or Corps) 

I was approached by a wholesale partner and flipper partners (whom I’ve done private lending for) of mine about me purchasing 1.5 acres to develop 12-16 single family homes on.I would be responsible for purchasing land and getting it prepped to build. 

I am hoping to find a single family home that I can "BRSTRHHRR" (buy, reno, Short term rent|House Hack, refinance, repeat) by creating a separate living space in a single family home that can be STRed (this is due to local restrictions in my town that prevent STR in multifamily properties). 

And that's coming from someone who thinks you can get by forming single member LLCs using similar services.

In general in single family areas they add significantly less value than the hands off cost to add the ADU.  

The firms that I go to for my single family properties only seem to do residential.

I'm new to the forums and looking to connect on single family long term rental deals as well as vacation rental deals. 

One has two single-family row homes a bit "over the line" in the Temple area.

.), are there any particular upsides or downsides of purchasing all single bedroom units vs. a more traditional mix of units for a property that size? 

Just a little background: I am still a senior in college, and I own a single family rental that I house-hacked last year.
