If you’re looking to sell your home fast for cash, you’ll need to be prepared to sell at a discount, and it's a good idea to understand what your mortgage balance is and how much cash minimum you need to put in your pocket after the sale. You still want the house to sell at a rate that earns you a profit or allows you to break even. However, the tradeoff with selling for cash is you may have to give up some of your profit margin or equity in exchange for the quick, hassle-free service.
Knowing this number ahead of time before reaching out to investors will be very helpful for you to speed up the process. It's also prudent to research comparable sales in your area, just so you have another data point. Just understand that these sale prices are typically gross and not accounting for realtor commissions, closing costs, and other fees. And if they sold on the market then they are likely upgraded in show-ready condition, so just make sure if your house is not that you account for that in the comparison.
