A low down payment conventional or FHA will probably be your best bet for meeting your goals mentioned above.

Thus minimizing the risk of being left with dead currency.Basically if you view Real Estate as a currency of it's own, I'd say it's one of the safest bets.

Blocs probably best bet for you if you have great credit

I bet we run into each other some more.  

I purchased this house in 2008 before the crash betting on appreciation and lost my shirt on the deal!

It sounds like you're best bet is to walk away.

U can hire folks  you see those rubber hoses across the road attached to a little box.. thats how they used to do it.I bet now its just a camera and wifi.. 

Welcome to BP @Giedrius Grebliunas  I bet we have other members from Lithuania here.

But your best bet is to have your cpa write up the taxes and before he/she submits electronically have your loan officer or broker verify that the income is acceptable.You'll need to have reserves in the amount 4% of all loan amounts of investment and 2 months of payments on your primary.So if you have 400k in investment property mortgage you'll need 16k in assets plus 2 of your primary mortgage payments saved up.I hope this helps and if you need a more detailed answer feel free to reach out to me.

My macro bet is on the waning desire of the American dream of home ownership and more emphasis on being mobile through renting.
