Investment Info:Single-family residence buy & hold investment.

Best option is likely to buy RE with an already existing detached ADU.  

I believe that will be a paint point for you and may be better to simply buy a recently constructed building where there's less risk and far less time involved.

A benefit to having the commercial property and entity is that we aim to utilize business credit, so that our personal credit and debt to income ratio is not tanked as we remodel or redesign or buy furniture. 

Throughout time, I'd like to buy my own equipment capable of doing the same thing so I can do everything in house.

That's the reason why despite 66,000 duplxes, there are barely any on the market (about 120 listings currently excluding the hood) - the reason is simple, you are basically an idiot if you are selling your duplex when you buy another house.

Would that make this a reasonable buy and hold? 

I've been a small time buy and holder investor for about 10-years and am now looking to supercharge this to build both a legacy for my kids one day, as well as a path to exit my W2 job.

If the numbers work, buy a place.
