I do believe Redfin/Xomee you could export the data and kinda compare contrast and Realtor you could do same just maybe in a zip code, county wide data. 

Hi Daniel, Our group has a wide rage product line to help investors with their financing needs. 

Here in Washington State there is a state wide fund that is used to deal with oil tank leaks; I believe that the fund is paid for by a tax on heating oil

Also, the denominator is "initial investment," not "total investment" I just get somewhat wary of inflated numbers that make something look better than it is -- saying that my NWROI is this incredible percentage - but an ongoing maintenance concern/capital expense actually makes the property break - -even or even worse. 

While I live in the greater Seattle area, I frequently travel all over the state, so I’m open to a wide range of areas.Thank you, and looking forward to connecting!

Since you are in NY or really anywhere Nation wide check in with @Joseph Chiofalo.

if you can build at 50% of after value I'd hire you and I build the cheapest of anyone I know in our market and minimum rates. there's 3 builders that build at our rate. only place I can get us to 50% equity is in miami florida and that is new construction that is selling at $1000 per square foot and up and high density 300+ unit underwriting with incredible economies of scale. columbus has lower construction costs but lower exit. we focus on urban core. my best suggestion is look at urban not suburban for higher valuations. you can't control what new construction appraises at so do it in less risky areas. 

LOL Jokes aside, it sounds like it's incredibly difficult to find something with good cash flow in Columbus, so my thought right now is to start in Cleveland for cashflow, then once I build a stronger porfolio I'll start adding Columbus

Also, any advice on finding and working with contractors would be incredibly helpful.

These are incredible insights and a lot of the things I have heard from everyone I have met in this industry.
