As an investor, you want to grow your portfolio first wide (number of assets, total property value), before you grow it deep (de-leverage, equity). 

Data generally has a wide angle of a market and lots of averages. 

Nonetheless, this could be a good deal for you and, as @Jay Hinrichs mentioned, a better deal in a retirement plan.Eyes wide open though.

- Do they focus on multiple asset classes or is it an inch wide mile deep, narrow focus? 

If not, another widely used one is dealcheck. 

Because state laws vary widely, my first thought is to talk with a title insurance underwriter in your state to see the requirements for insurable title on a tax deed.Quiet title may not happen "automatically".

I’m assuming you’re talking about mobile homes, like single wides and double wides?

Unlike, an independent GC, who undertakes a broader array of projects, Curbio’s project experience will be more uniform and consistent over time (e.g. focusing on a core set of projects, with similarly attractive traits: impactful; reduced complexity; reliable sourcing; etc.).The “as-is” investor approach that you describe should work, as you would have all of the criteria necessary to be deemed a “qualified-prospect” for Curbio, e.g.: sufficient equity to cover a min $15K budget and ample up-side potential to deliver a sufficient positive ROI.
