With actual cash, you just transfer it. yes, but you can still bid with lender approval - without appraisal contingency - you send in deal (app), it gets approved by lender its functionally the same as cash (except in true lightning speed situations where there is a quick auction with little time to prep but thats generally pretty rare I'd think)Right, but that's not cash or functionally the same as cash because the lender can change the terms at the last minute, as often happens with less experienced hard money lenders.

But, if you do evict AND they request a hearing then the judge MAY interrupt the partial payment as acceptance of rent and therefore you would have to start the process over at the beginning of the next payment period.

Like you said, you don't want to grow super fast so take your time and watch the mortgage markets.
