I am wondering from a buyers perspective, it is better to have higher buying price or higher interest?

It sounds like there's a good scope of upside but thinking from a lender perspective and dealing with many investors, I'd recommend you need to work your numbers backwards and see what your upside looks like, based on realistic income and expenses and then go from there. 

But sometimes the sill or edge pieces are gone too, and then the whole house can shift. 

And if you have a totally different perspective, I would love to hear that as well. 

However, shifting equity can't help you if the main problem with the mortgage payment are the property taxes and insurance coverage of your new house. 

You can refi later, but sellers are getting scared now, so negotiate as the market shifts.

(These issues have been discussed on a variety of recent BP podcasts, and probably also in the forums if you want to read up).So, to answer your question: even if air dna was accurate several months ago, it might not be accurate today, because the market is shifting so quickly and their data might be based on market dynamics that don't exist anymore.

Look at it from a renter's perspective.
