Visit www.fanniemae.com for more information. Search support for renters. Following are some points on the program.
Some criteria follows:
1. To Qualify, a renter must live in the property when it is acquired by Fannie Mae
2. Fannie mae will not require security deposits
3. Under the Fannie mae lease, the propety may be marketed for sale and if sold the property would be transferred to the new owner subject to lease
4. Rental rates under the new leases will be comparable to other rents in the same market and subject to any legal rent control restrictions
