FHA homes are all over my area some with very low prices in good neighborhoods, my question to you is for example a $230,000 3 bd 2 bth is on the MLS and FHAHOMES sight in my area, been on market for over 3 months, i would like to bid on, but willing to fork up $500.00 earnest money hold before 30 day or even 7 days closing date and double close to another buyer, can this be possible with an FHA.
