what could be a possible partnership model with local experts? 

I have a 9-5 that I want out of but want to secure at least my first property prior to leaving it.

Given that the house is paid off but has $27K in back taxes, you could offer to cover those taxes upfront in exchange for favorable terms on the remaining balance—like low (or no) down payment, and small monthly payments.You could also negotiate for a subject-to deal where you take over the property subject to the taxes, while still securing control of the property for your BRRRR strategy.

Will this affect her survivors benefits social security income? 

Alternatively, you could take a loan against your 401k for that initial amount.Once you’ve secured the property and paid the 5%, you can then work with a private money lender (PML) to close on the property once the deed is ready. 

Outside of real estate, I'm an entrepreneur and 3D Landscape Design or Outdoor Living Luxury Expert. 

I'll pass.Very rookie question for you, @Patrick Roberts and everyone else here: I thought that post-Dodd-Frank, the barrier for mortgage lender accreditation/licensing was essentially raised to a point that HML’s and private lenders were effectively iced out of securing loans with a mortgage or DOT.

Another option may be to secure the loan using primary residence as collateral. 

Each loan type will also have a number of fees that you will need topay to secure the funding (eg. you will be paying the broker for commercial,whereas the lender pays the broker in residential financing).My best recommendation is to talk with alocal commercial mortgage broker specializing inmultifamily lending.
