While you may not have learned much about real estate you have learned a lesson about life and business.

If you have enough money but your business is the main driver of income in most cases you can make more money putting time into the business.You could also get creative here.

There are some great on-line real estate courses, and I have found the information within them has really been helpful for my investment business.

Also, consider who you’re hosting, is it families, business travelers, or medical professionals?

Working this backwards, what I see is a 3rd party trying to benefit from another’s house via rental cashflow, My only business is 30+ years as probate estate and trust lending in CA.

Of course, the smaller the property, the more necessary that you see every inch of it because there isn't a business running on top of the land like large-scale multifamily, self-storage, industrial, and more.

I'm making some pretty big moves right now and changing my business plan in a new direction, so I don't want to die of shiny object syndrome, but this method really speaks to me.

I have an Acquisition Analytics service for Business purchases that are under $5mil in revenue, that I do with my Bookkeeping Firm.

A Qualified Joint Venture (§761(f)(2) )allows two spouses operating a business together to not file a partnership return; however the business can't be held as a state entity (§301.7701-2) like an LLC and it also requires material participation by each spouse under §469(h) which can be hard with a SFH. 

First of all, do not take any money out of the business, because you will need it.
