Housing is a necessity so as long as you are in a decent area for rentals it will rent, but it will come down to price.

What's your end goal —cash flow or long-term generation? 

We are closing soon on a multi use building, we plan to live in the apartment but it needs a complete rehab.

Don’t forget, we are hard money lenders, so we are used to financing borrowers who aren’t necessarily strong.  

I'd prioritize finding long-term, reliable tenants who will treat your property with care over the quick turnover of short-term rentals.

A home run between 15% and 20% and, if above 20%, a grand slam (as long as the market holds).Is it fair to assume 50/50 split of net profit at closing?

How can I get there and how long would it take?

As long as the property is in good shape and is able to market itself in the event of a vacancy, then I think you've got a stable, good performing asset. 

If you flip a house with in a year and incur a tax rate, “ordinary income”then does all of your other income from your rentals “long term income”get taxed at the same rate as ordinary income?

It has worked great for me.The only downside I see is the potential for damage and also the long orientation that has to be done if renter's haven't used an RV before.My wife and I considered buying an RV to mostly rent, but decided not too as they were very hard to purchase last year.
