Refinancing  immediately prior to a sale - yes that is a cause for some seasoning. 

What is your anticipated sale price?

So selling it to someone when you can't give them clean and insurable title can sometimes be an issue.At that price point, not so much. 8k properties tend to have a buyer pool that won't care as much that the title isn't insurable if they see the reason why is because it was bought at a tax sale. 

Much of this analysis is based on the size of the land, how much it will cost to do the horizontal development, and then estimate the cost of the vertical build and ultimate value (aka "sale price")

X a month sounds a lot better and is actually doable for a lot of people vs a big pile of cash today if you need a full cash sale. 

I do plumbing inspections on the way in, along with full home inspections, and sometimes we do a pre-sale home inspection on the way out before the sale and we offer that as part of the listing package.
