If it's not a holiday, I would say, "No, the deposit remains in place until your lease ends."

How to match them and where to get them?

I’ve never had a problem with a lender when I showed them the deposit that was made into that account.

You can create an account to advertise yourself as a host or a guest (or both) and get matched with others.

You can not do a pet deposit unless your security deposit is less then 1 months rent.

deposited in a demand deposit account?  

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

An agent with market knowledge and deal flow that could present us with off and on market properties that match our strategy will be needed.

And not to mention no stock matches the dividend rate one can get in real estate with such low risk/volatility. 20yrs ownership, oh-yeah, cash-flow on renting it would be HUGE now so it's easily comparable to a 20%+ monthly dividend, if not more.

If the answers match, you’re probably in good hands.
