The estoppel is a form filled out by the tenant, then confirmed by the Landlord, and then accepted by the Buyer.

Can I ask for credit up to the amount of replacing the hvac system which I doubt the seller will accept or just pull out of the contract?

Run owner reports.After testing a few apps, one of them should stand out for you.

Now is not the time to “test the market” with an ambitious price to “see what happens.”

HUD provides the list to their Section 8 clients for properties accepting Section 8, but it doesn't have a good reputation.

I wouldn't be super punitive on this since you continued to accept payments monthly until they wanted to pay off.

If everything else looks good, I would probably accept them with a double deposit.

I do find it hard to believe the seller’s expenses unless they’re backed up by some official documents but unfortunately I’ve read that I could only receive them after an offer has been made and accepted when I’m doing my due diligence.

Kevin If you don't currently have a down payment, you negotiate with the seller as to what is acceptable to them.

This is much more cost effective and should be considered up to code unless your town has codes that are stricter than the nationally accepted building code.
