salo_t, what you’re doing is smart so long as you’re putting down 10% or less (money which you’ll no longer have use of). Don’t forget to add property taxes to your calculations as well. You might just get someone to bite.
Don’t worry about hurting the sellers’ feelings. We live in a capitalist society and a deal’s a deal.
Please let us know if things work out for you. Also please tell us about the funny/interesting responses from the sellers’ agents.
