We spent a lot of time and effort on studying the market data and purchasing review-based data from top performing properties and from super-hosts all over the country.

You are scrubbing the data anyway so why not make it count?

I am trying to understand how to get an accurate cap rate and other data for this market?  

To get this type of granular data would require diving into foreclosure notices, tax assessor websites, etc where you live.For example, I buy foreclosures in Arizona and Wisconsin.

I just don't feel i am ready to do that right now......but I met a GC who is willing split the role with me to reduce my cost.

You will want to work with a lender who can prequalify you for a loan amount and produce accurate estimates of the upfront and monthly cost associated with a loan, and a realtor who can provide you with accurate market rent data on comparable properties.

This data will be used to prorate the purchase price based on the relative fair market value of each of the components.

Has anyone else noticed the same level of differences in data accuracy, or are there any recommendations on the most accurate driving for dollars apps that automate the manual skip tracing process?

Most auctions are going through auction. com and they have a good calendar.The other site I use is a foreclosure website, its nationwide, I pay for just one county for the auction data and their calendar is superb.. you can pay extra for more counties but it starts to get a bit pricey.

Conversely, an experienced realtor will help save time by helping you establish price based on recent comparable lease data, which can be challenging if your development is the first to come on line in a given area or if the market is going through a shift.
