There's also the danger of the tenant doing things you're not aware of because they're far more isolated and have more privacy. 

Also, very important, is to realize if you get into a default situation on your HELOC, they will come after your personal house... so there is a bit more "implied danger" in the event of default... you don't lose the rental you bought on credit, you lose your own house!

When you Do move out, there should be less urgent maintenance issues (or fewer surprises).

Besides the possibility of this falling out of contract, there is also the danger of this being wire fraud.

We’re seeing a modest increase in days on market, fewer active buyers, not as many offers on a listing, etc.We just put a property in escrow while representing the buyer, and the seller sent us a counter offer – not a multiple counter offer.

It will however cause fewer deals to be good deals.

The hedge funds will be able to pick up the $400k homes with less competition and fewer bidding wars.

They could be awesome and not have much to work with in the way of offers- usually that's because you are priced too high, but did the advise you of the danger of a low appraisal and try to counter your offers to protect your interests?

There are fewer bidding wars than March and April. 

...that... and my concern that there would be fewer people that would opt to rent a house for $1800 instead of getting a mortgage for $1100.
