Hello,I am a Software Engineer and a Real Estate Investor working on a tech product for the real estate mortgage brokers.

Are there other options that could be better for a construction to perm loan (not through a traditional bank)???

Many construction companies already have someone who does what I do and other contractors apply for their own permitting for their projects.
