If the permanent financing will allow you to recover most of your initial investment and the fair market rent covers the principal, interest taxes, and insurance with cash left over, you have a BRRRR.

Most of my renters are nurses, engineers, and tax payer funded employees (Government workers). 

My question is can anyone point in the direction of someone who could represent me in this matter maybe a lawyer or attorney, or someone who knows the fire code and who can be clear and concise on what I need.

For example, you could create a weighted structure where a percentage of profits is based on cash contributions, and another portion compensates for rehab or management efforts.Rent Payments and Tax-Free Profits:If you structure it as an owner-occupied property, the rent you pay could be shared proportionally, but tax-free gains on resale may only apply to your share, as you’d be the owner-occupant.

We have sold (tax free), kept as long term and/or short term rentals as well.

Talk with a real estate lawyer as this may work a little different in each state.
