NO foundation perimeter wall only post and piers

[Loren Becker]

Hi experts,

I purchased a home to flip in Lennox Ca 300 Sq Ft and there is NO perimeter foundation wall.  the home was build tin 1938 seems

straight and level, but no foundation walls. My concern is after rehab if HUD or other lender would not fund a loan with older

type  of foundation?

Thank you,
