I do / done many rent to own (contract for deed) and a few seller finananced deals where I keep the note.Why not in parallel use a flat fee listing on MLS too?   

Operating within California means you’ll need to register any LLC conducting business in the state, regardless of where it’s formed.

Where are your properties located?

In addition, if this was originally an owner occupied house, there are often homestead exemptions where the first  $XX,XXX. of the value of the home aren't taxed.  

Once you go above $125k/unit you start to get into the high end areas that won't have very good rent/price ratios and are under the 1% rule mark for turnkey stuff.Neighborhood wise in the city the "East End" is where the most expensive real estate is since that's where the universities and a lot of the hospitals are located.

You could also use "Doug's LLC and/or assigns" where Doug's LLC is your hypothetical company.As for the assignment contract, you can get one from an attorney for probably less than $1,000, you can also make a friend at a title company, they probably have a template they could give you.  

I'll add on to what the other Ben said and mention that there are exceptions based on the # of days that you rent out your home to where the income/expenses are excludable (being lesser of 14 days or 10% of total usage if under 140 personal use days).

CT isn't cheap so if you plan on doing it there you are going to surprised at how poorly you do. maybe in the suburbs I'm not sure but as much as I know people call us from CT and everyone is rich and has lots of money and things are expensive out there. build to rent is a great model. we build 3 story walk up infill and keep it to the residential side. 3 units is the most units before it's commercial and you need engineering, etc. check comparable and things liek that. we came up with this design a year ago and we sold 10 if you want to talk further please DM me happy to connect. there are some great build to rent conferences. we went vertical not horizontal with it to save on build costs and design to fit on any infill lot. this fits on a 3500 square foot lot. most lots in our area are 30x120 or 30x150. in miami where I live now they are 50x100 or so. but any infill lot we can pretty much get this one on. there are some great build to rent conferences coming up too that if you like this topic I'd recommend attending I'm sure you'd learn a lot. 

@Vina Merrill,Went to college in Knoxville, current a BDM in Chattanooga, where I'm from.

Where do you live, and where are your units?
