We do have some small grading issues around our house, and have experience backyard flooding once with some water flooding into our crawlspace.

Living out of your car, couch surfing at friends, living in the shed of someones back yard, live with grandma, live with mom and dad.

You have a limited buyer pool, your upside is small, it could be protracted and expensive (surveys up here cost $1200-1500), if Edmonds claim a right to it, the legal fees could escalate beyond what the property is worth in less than five minutes.I'd see if they will buy your position as-is. 

It is likely more useful for long distance investors than it is for those investing in their own back yards, but a useful tool nonetheless.Is there anyone who can attest to the accuracy of its ratings?

You will have a much larger pool of buyers.  

If so, you open yourself up to a larger pool of candidates. 

Another option (which from your posts, doesn't sound like one you would like to entertain) is speak to a lender that offers a portfolio product where you can pool properties valued at $72k - $99k together to achieve a total minimum loan amount of $300k ($50k per property). 

This eliminates the four kids wanting to pool their money and rent something they can't afford which is always a mess.2.

I'm trying to find private REI clubs that pool capital together for better purchasing power/due diligence efforts/etc. to invest passively in RE syndications (multi-family, development, mobile home, self-storage, etc.). 

When I had bought the building 2 years ago it was winter time and the entire back yard was dog crap from someone's emotional support animal.
