This allows us to close extremely quickly, which is an important competitive advantage.I don’t know how to read our own tax returns, and I’m certainly not going to read yours.

Whichever loan that you decide to use, the interest will be tax deductible due to interest tracing rules.

I paid tax on it and mowed it about every 5 years so maybe put 10k into over the years.. deductive reasoning suggested city does not build and full blown interchange to go to nowhere. 

It links to our business bank account and our business credit card so come tax time, deductions should be easier.

Another downside is you loose on the advantages, of the Federal Tax Code, by not closing in the name of a LLC (you can elect to have a LLC taxed, as a S Corporation which is a whole other conversation).If you want to close in the name of a LLC, Mortgage Lenders will offer you Commercial Loan Terms (25-30% down, a 15-25 year amortization, and a ballon due in 5-7 years).

@Nicole GrazianoI recommend that you have a consultation with a real estate tax accountant regarding your taxes.Bigger Pockets is a great place to find a real estate tax accountant. 

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

The property was rented and generated $160 cash flow after mortgage, taxes, insurance and property management fees were paid.

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

They are grandfathered in, the property was built prior to those standards.
