Number of Units
Fannie Mae purchases or securitizes first-lien mortgages that are secured by residential properties when the dwelling consists of one to four units. Under some circumstances, Fannie Mae limits the number of dwelling units for certain types of mortgages or transactions. For the maximum allowable LTV, CLTV, and HCLTV ratios and credit score requirements based on the property type and number of units, see the Eligibility Matrix.
