Hey @Guang Yang, no need to use any kind of extra stuff for a single unit like @Patricia Andriolo-Bull said.Just use the built in tools on VRBO and AirBNB and you will do just fine.

I didn't even know you had replied.

Evicting them, even after purchase, could be a lengthy and costly legal process.

We have a single-family residence we own and have lived in for a number of years.

The duplex has been sitting for 90 days and is 3 times more than All single family Homes with the 3 beds and 3 baths in the neighborhood.

would you still create the single LLCs in OH (the state where the flip is in) or open one in my state of residence and JV with the local LLC ?  

While I don’t specialize in multifamily properties, I have worked with many investors in the single-family sector.

You want to look for like/kind SOLD properties to compare so, single family to single family and multi to multi (2-4). 

Not even the stock market (as long as the rental leveraged).   

I'd recommend looking at costs. your build cost is going to be well over other homes because of the fixed costs like slab, Hvac, roof, etc. check the market drivers and weight the benefits of short term versus long term. long term is no furniture and help pays mortgage but at this size it doesn't really cover everything. we didn't find a lot of economies of scale in single family detached. can you build more than one unit?
