>>Even if you get the mortgage, it's the same as cash to the seller.

Not really, pay in 'cash' and you can close in days, pay with a mortgage and it might take weeks to months. Sellers always prefer cash buyers if they are in a hurry to sell.

No. In the US standard housing purchase agreements are drawn up contingent on financing - and standard bank financing has a lot of hoops and procedure to go through - it usually takes at least a month and of course it may fall through. During that time the seller is basically sitting on their ass and can’t advertise the property.

An all cash deal means the seller does not have to wait once the parties have a mutual purchase agreement.

Sure if everything works out then the seller gets the same, but there are many more reasons a financed offer will fall through versus an all-cash offer.

Absolutely. You won't believe all the crazy stuff that can happen that makes an offer fail when using a mortgage.

I just bought a house in cash, the seller wasn't willing to accept any non-cash offers. With a cash offer the seller and buyer can close in a significantly shorter amount of time than with a mortgage.

Banks pre approve liberally but commit to funding with great deliberation. It isn’t the same thing because banks can make all sorts of deals fail.
