And the Asian purchasers will search on web pages about news articles about the property too, so if the deaths were in the news, they may find out even if you do not disclose.

Just get a carrot.com webpage. 

Since no paychecks are guaranteed I’ve decided I needed “x” months saved.

Retired parents have $1M liquid cash in the bank, looking to buy a $500k home with 20% down.Clearly they have enough to buy in cash, but the plan is to use other peoples money and have the rent cover the monthly payments.There's no income, but if banks could somehow quarantine some of this liquid cash each year, they would guarantee no default in payment.Is there a low interest rate loan they can get?

Typically yes, you’ll be signing a personal guarantee, so it will affect your credit and DTI.

It's no guarantee but it's a good place to start.

However you will not be able to get a guaranteed price until they visit the property as a GC will see things you do not.

I guarantee 1000% you will regret not buying it!   

Its important to remember that it is all subjective and nothing is guaranteed, but Im a firm believer that there is money to be made everywhere.

Thanks in advance.The world wasn't invented yesterday, unfortunately for you: The seller has a contract with the listing agent guaranteeing her a commission, paid by the seller.The Redfin agent has "procuring cause" for this property, guaranteeing him a commission should you buy this particular house that he showed you, also paid by the seller.
