Me and my girlfriend are currently saving to purchase a home within the next year or so to start house hacking, my concern is how signing the lease option to purchase contract will affect our eligibility for first time home buyer programs? 

Programs that market themselves as shortcuts often cannot replace the depth of understanding that comes from study, experience, and engagement with the legal framework surrounding real estate.Consider taking time to familiarize yourself with local laws and regulations.

DSCR is a program not a lender type.

A non profit school program acquired the assemblage 30 years ago and built an infill structure and an addition in the rear.

Often low down payment/no PMI programs have those costs built in elsewhere in the loan. 

Thanks for the details on the rental program too.

Networking is huge, so connect with others in the industry, and look for mentorship programs (there are some great ones out there).

I always get a notice to pay for the "Proactive Rental Enforcement Program" https://www.santa-ana.org/prep-program/. 

@Jay Hinrichs is correct.However, the following seasoning periods are what I am working with on the DSCR programs that I utilize for my clients.

But I was also sent a document stating that a county housing assistance program was guaranteeing the tenants security deposit (which was accepted by the current landlord) but not for the full lease term because the tenant is no longer receiving assistance and that the guarantee would only be until 2/2025.
