Arrington Investment Properties,LLC. When you contact us and submit the short property information form (below), we’ll give you a fair all-cash offer on your house within 24-48 hours… and the best part is: we can close whenever YOU choose to close – it’s entirely up to you. It doesn’t matter what condition the house is in, or even if there are tenants in there that you can’t get rid of… don’t worry about it. We’ll take care of it for you. And if you need the cash quickly, we can close in as little as 7 days because we buy houses with cash and don’t have to rely on traditional bank financing.
