I’d like to have 3 single-family homes and the 5-plex paid off by then, which would give me some solid passive income.

At the end of the day if you run your numbers and analyze like 10 properties a day, and every single day scour the internet for anything new, you will eventually find something that works and know it almost immediately.

The last year I renovated a single family home to rent, pulled out some equity, couldn’t have gone better.

An example was a line item for alimony (I am single and have never been married).

it will be a corporate/wellness retreat/short term rental destinationI need land that is close to the Action, but not too close, and preferably comes with two single family doors already built, so I can take advantage of Fannie Mae owner occupied loan and develop the rest of the land on my own and with private funding.Is Columbus a good market for this strategy?

I just completed an exchange of a single family residence in Scottsdale to a single family residence in Durango, Colorado. 

Rental rates are fine for SFHs - I haven't had to drop my rates whatsoever with turnover, nor have I had a single tenant try to negotiate a lower rate. 

They knew all along this was an LLC, every single paperwork sent to them was under the LLC. 

Other option would be to sell one of these homes and buy a single family home on a larger, flatter lot with more potential to build, but then I lose these great mortgages I've got.  

Quote from @Zach Howard: Quote from @Jonathan Greene: If you are looking at properties in the US only on Zillow, and not seeing them in person (I know you are in Hong Kong), this is just an effort in futility because you can't underwrite single-family or small multifamily deals only online.
