Yes I was a little suspicious of Thumbtack which is why I started asking around and was looking at Google and Yelp reviews.

Outside of looking suspicious without a return address, you want to know when an address is undeliverable, or when the people are not where the tax man thinks they are.

It's honestly making me suspicious of their honesty from the start - surely they should have realized this fact long ago already, being in the market for 8+ years?

Neighbors said that there had been scary suspicious activity in the home for most all of 2019. 

Boats for investors is a scam, you're right to be suspicious.

I would use it to check the tax records for suspicious sales over the next 6 months.

Loose animals, trash in the park, bandit signs, people acting "suspicious" by walking down the street and "looking at houses" (not sure what else you're supposed to look at in a residential neighborhood, but ok) or driving down the alley (which all the garages face to).

The main reason was some idiot mobile notary wouldn't sign the document b/c she all of the sudden became a lawyer and said it smelled suspicious...what a crock!!

I think I'd be a little suspicious about someone who's doing a direct marketing campaign to buy their own home.
