FHA loan limits have been increased dramatically and that includes the 203k. Some real estate professionals are missing the boat with mixed use buildings, warehouses in residential neighborhoods, and larger income units from 5-8 units... all of these are 203k potential. 

Warehouse - turn it into "Live/Work" units up to 4. Yes the owner must live in one unit but many people would live in a "Live/Work" unit know lots of other people who might like that too and become tenants. The additional rental units add income to the borrower's other income. If they can qualifiy for a SFR then they will likely qualify for this.

Mixed Use - ignor the commercial and work with up to 4 residential units in the building. If you could steal a 3 story building with multiple units... make them flats with commercial on the bottom floor only...
