I either use all cash or have been able to purchase 100% ltv via local credit unions.
I'm not "out" anymore than you and probably less as I'm only paying a couple months of interest. Like I said, I only have to go to them once and not come back in four months, pay penalty etc etc. In your scenario, you are paying interest (+principal?) monthly, plus you have to pay the penalty. Another reason is if a really good deal showed up on my doorstep today (that either came to me organically, or I've uncovered), either off market or on market, I can close extremely fast if I need to to get the purchase. This can be extremely enticing for some owners who need/want to offload immediately and if they have a buyer on the table with a cheque (and maybe not conditions) verses another offer where there are financing conditions etc and the time it takes to satisfy those conditions and the risk that it may not go through, I have a significant advantage.
I recently was presented an off market opportunity as the person heard we had some rentals. They said we just want the house gone now. I probable paid 40K less than market value but I was able to just hand over a cheque. They were happy they had quick easy sale. I was happy I got a great deal.
Yes, I forsure get your point of "missing out" on other good deals during this time period. This is very valid but for me, at least at this time. I can only do/handle one opportunity at a time.
