There's been quite a bit of cap ex as well as a recent $2,000 assessment per owner to begin a rebuild of the exterior steps at the complex.  

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. 

My all in cost would be $170-175k and I could get $1500-1550/month based on comps and data from my PM.

As a Data point we are now seeing this in High priced markets with ultra liberal cities not prosecuting crimes of less than 1000. 

More quantitative data you have the better you can measure your return.- What is my time horizon to hold?
