I don't know that I would gamble and say you could sell it if it doesn't work out, you could be holding it for some time.

This is the smart thing to do but I've been doing this 25 years and I'm tired of worrying about this crap when I'm off shore trying to catch flounder. 2. 

Which is not true and riskier to only gamble on appreciation I think.

I've lost money on deals that I took a gamble - Detroit homes with more taxes owed than the value of the property, and I've made money.What else can I tell you?

Otherwise, you are just gambling that the bank will not call the loan if/when they discover you have left the property (which probably states it will be owner occupied in your loan, if it's a primary) and are no longer making payments. 

If one has to take care of other family members, then that adds another level of stress and complexity.If someone is on their own and wants to gamble, sure, some will take a shot.

You'd be better off just investing in one of the many note funds rather than straight-up gambling for a couple hundred extra bps. 

I'd probably have better odds going to a casino and gambling.

The 350k will earn 15-20k/yr recouping a good portion of the gambled amount. if that works out do it again.

If you're OK with a gamble for higher % gains, that's what we have done with a big chunk of our cash.
