If you can qualify comfortably and are willing to take the risk, then jump.Another option is to get into contract to purchase the new house, close and then sell the existing one which mitigates (reduces) the risk of owning two properties in a market that may decrease in value.

Does anyone know if a place exists where I can filter out transactions that aren't cash financed?

I wanted to check what effect the existing availability of homes will have on current multi-family rentals like the duplex in question.

So making one now and paying the whole fee for its existence for a month doesn't sound that appetizing.In my layman's opinion, I don't think there really is a difference, other than the California issue. 

But I’m in Des Moines, Iowa, not California, so the backlogs that we’re spoken of were non existent.

I prefer existing assets because there is in-place cash flow and when markets turn, developers tend to be the ones left out in the cold.
