Okay, not really. $5,000 a month, must be a *heck* of a place. $2,500 for the new one, you must be putting down a *heck* of a lot of money and/or it isn’t half as nice as the place you’re renting.
I don’t care how best a price you get on your new place, you’ll be losing money and regretting it in the future.
To answer your misguided question though, I wouldn’t expect that you could get more than 10% below asking on a place, and less if the seller priced it right in the first place.
If you’re thinking you can take advantage of the deflating bubble to get a better price today, sorry you can’t.
