And how realistic is it to move into such a building for long-term rent?

Realistically most banks would send you a warning letter if you were doing something they didn't like.  

Realistically it's going to be difficult for you to actually collect the remaining rent amount if the tenant refuses.

You might have an expectation of 30-90 DOM to sell a property in the US meanwhile you are realistically looking at 6-18+ months in DR. 

I wake up from my dream, and start being realistic.

We couldn't quite move there full time in the near term, but a realistic gameplay would be at least 6 months per year within the next decade to take advantage of the tax incentives.

At 40% expense ratio which is more realistic you effectively need the Gross Operating Income to equal 2% of the asset price.

So they would be very hard to find them or have them work for you. expecting residential real estate agents to be experts at income producing properties is not realistic and not advised.. if your looking for investment property you should only be dealing with investment brokers .. there are designations for them or resi agents with the investment designation.. 

Realistically you're probably taking a haircut on these purchases, and definitely continuing to lose money every month if you keep them.
