Questions brokers ask.

Do high-balance multi-unit loans use the 95% limit?

No. The JMAC Fannie Mae matrix limits high-balance two-unit loans to 85% and three- to four-unit loans to 75% for the listed purchase / rate-and-term structures.

How do manufactured homes differ?

The matrix has separate manufactured-home credit, leverage, occupancy and term limits. Manufactured homes are limited to conforming loan amounts and primary occupancy.
