Just tell her that you cannot afford anything more than 300k and you don’t want to insult her with an offer that low, she can’t take offense to that. The other posters are correct in their assumption that she probably can’t sell it for that because she owes more, has cash flow troubles and will be letting some of her rentals go back to the banks. If she is in the new home industry she is losing money on her rentals and isn’t making much at work to cover it, she acts loaded because she used to be. You can also ask her if you can stay after the lease runs out until it sells. Ask for a 40% reduction in rent and agree to hire a cleaning lady to keep it nice for showings. Since you won’t have the comfort of a lease and you will have to deal with showings it isn’t worth full rent. She will want you to pay full price but that isn’t fair to you and her cost to have it empty will be astronomical and won’t be able to get a new renter, so you are her only chance at any cash flow. I’ve noticed some crazy bargains in rental houses because they are also for sale.
