The lender should have told you; you didn't order checks so you might push back on paying for them. 

If the "heir" is pushing for this, beware!

The tax rolls, Zillow or market analysis, are often WAY off.And the licensed appraiser can be off buy a bunch, too.

I could also roll my 401k over into a self-directed account, but I think I would have to pay taxes on that immediately (I could be wrong) and just purchase and rehab the rental in from within my account?

I was pushing it with my initial post.  

You could ask to see the rent roll or deposit journal and you could check 'rentometer.com' to see if rent is at market.

It’s so exciting but I know there are going to be rough patches, we’ve just gotta push through them and thanks to BP and everyone on here it makes it seem a little less worrisome!

Original Projected sale was April but it was pushed back due to Covid, so we started selling the beginning of October 2020, had a good offer within a week on the market, Agreed with the price and contract was signed last week. 

It would keep your costs down (especially right now) so you can cash flow higher and pay it off quicker.Another route you can go is to utilize the Infinite Banking Concept to push the cash into the policy to kick start the compound growth and then borrow against it to buy the house.
