There was a guy here who described this as his number one lead source for investor money on multiple podcasts.

Feel free to reach out if I can be of any assistance, I can refer you to a couple different sources if interested.

Zillow's API is no longer offered (or they make it extremely hard to access these days - have had no luck finding an updated link/page for it), Redfin has broad-stroke CSVs you can download that only give 5-10 fields of info and not often at the metro area, you can't legally create a tool to crawl these websites...I'm looking for 1 (or a handful of sources) to pull together basic metrics at the metro/city level for US real estate.

You already mentioned you have the cash flow from other sources to live. 

@Amber Douglas  Usually for small loan amounts like that your best source will be small local banks or credit unions that know the property in question.  

Rehab in Pittsburgh PA: looking for a good source for decent quality cabinets already assembled, any insight on a vendor other than Lowe's or HD?

Finding the deals requires some savvy marketing, and sourcing methods.

You want to be sure the parking area and/driveway is also not too steep.Also, as evidenced by the last 10 days in the area, be wary of anything on or near a water source or low bridges and such to get to it.

If there isn't one website or source, what is another method other than looking at the competitors?

Did you end up finding a source?
