Construction to perm loan for multi-family possible?

I'm trying to add a mezz level of debt to reduce my equity raise/increase IRR and wondering if any lenders to construction-to-permanent loans on multi-family residential buildings?

Thinking if I can raise the necessary deposit first, get the const-to-perm loan, start demo and building while I work on the MOU permit (turning the building into a boutique hotel), keep raising for the soft costs. Plan is to have the MOU in place at the 24 month period and refi into a SBA 504 for the soft costs and furnishings to launch the property.

Is this doable? I mean, I know it will be complicated and the timeline will be tricky and nothing is guaranteed. But does such a loan exist? Anyone have experience doing a similar deal?
