Are all foundation concerns a "no go" or are there levels to this?

Such a no-brainer. 

Its a no brainer!

Never accept a NO as a final answer.

But I personally wouldn't want to hold the bag waiting for a developer to come along and want to buy the land, as till then I'd be bagholding it and having a negative cash-flow from it.In terms of small plots of land being purchased, a few acres or less than hundreds, I don't believe it's a good investment whatsoever as the land value will not rise unless development occurs, and development will only occur if a large amount of land can be purchased at once, and if development already occurred and you're buying a plot in a paved planned community I believe the price of the land to be priced in.In short: Small plots are a no go for me, I'd buy a small property instead.

If they have any ownership during the construction process or have made any payments to the builder, they need to have a Builders Risk policy or be named on the Builders Risk policy their contractor purchased- Medical Payments coverage is a no-fault coverage used to pay medical bills for small claims to avoid them going to litigation.  

Or a no personal guarantee?

Google "IRS EIN" for the link or go to https://sa.www4.irs.gov/modiein/individual/index.jsp (current link today) Remember that every year you have to file a "no tax due" or your account becomes in bad standing (as what happens to me all time since I just forget).

Most of the time I pitch this at the listing presentation, it's a no-brainer for the seller and they love it, just looking for more.Currently we are sending mailers to absentee owners, social media marketing and homes around our recent projects.The product - We offer a product through an affiliate business for our sellers that would normally be the target of many wholesalers. 

As many said, I would also opt as a no, but you can explain to them why you wouldn't want it painted (needing it to be primed/colored/sealed, if the color has to be approved by HOA etc)
