One more thing, if your grandmother is not able to sign a Warranty Deed, you can have someone appointed as her Power of Attorney to sign on her behalf.

I was not able to sell it as the summer market had passed so I have rented the place out for the last year.

But I'm not able to put a place under contract because I just don't have the right key players.So I want to put this out to all the virtual wholesalers out there. 

I am not able to get into the property as it is currently occupied.Any tips or further due diligence I can do before the auction?

Since we're still fairly new investors (and house #2 didn't give us as much profit as hoped for since the market went down quite a bit during the time we owned it) we are trying to stick to properties that we wouldn't mind living in if for some reason we're not able to sell it.

Also, I factored in that if I was not able to find a suitable replacement property in 45 days and also close on the new property in 180 days I would face significant capital gains taxes.  

Also, if you're not able to succeed with the rental aspect would you be able to sell?

As a non-american, I understand that I am not able to apply for the Crowdfunding program.  

Most notably, we just completed a full rehab with a similar scope as our first project.

You'll likely get stuck with the house and not able to sell it if you have to.Other than your knowledge of the area, you need to either get the help of a real estate agent or pull some comps yourself to support your decision.
