Both programs allow you to export all your data so that you can forward to your accountant.

No need to give them all your data. 

I feel this house is going to increase in value tremendously over the next 10+ years and really don't want to give it up because my ex wants off the mortgage and I don't have the upfront cash in order refinance. 

So ask your questions, get your data and do your research.

This will allow you export the data so you can run a comparison analysis all in excel.

Hi @Sarah, The best resource I've found is Zillow data. https://www.zillow.com/researc... 

I've tried to gather data via a tool called Mashvisor but the platform seems buggy and I'm not sure if I can trust that data.Aside from manually scrapping info on Zillow, Realtor.com, etc.

Verify all the data on the app as best you can.

I've also polled several of the people in my network (contractors, flippers, wholesalers, brokers) asking what they are seeing.Below is my updated budget (padded) for Spring/Summer 2021. (1) Note that the 2020 numbers are a padded (I pad everything) high average of budgets pulled from 4 houses I flipped in the PNW in 2019-2020. (2) If the official numbers were below inflation, I used Inflation (Shadowstats.com). (3) The overall increase in price on my breakdown is close to the overall data I've found online, which makes me think I have a decent updated budget for eyeballing deals with. (4) To reiterate, the numbers I started with were unique to my situation in the PNW, so please don't take them as gospel for you!

I can't speak to the accuracy of AirDNA's data, although I think it has gotten quite a bit better over the past few years.
