Hi @Sang JiGenerally there are two options 1. 

I also want to get into rental properties and I'm chasing down whether veteran SBA/504 is a viable option.

These loans often have interest-only payment options, meaning you only pay the interest for the duration of the loan or a shorter period based on the market conditions.

I'm unsure how owning this commercial property will affect my financing options for the personal home.

FL is also the toughest state in the country (based on my experience) for reliable contractors.If you don't need a ton of house, you could find a nice option for yourself and try to get a small rental.

I am weighing this option against investing in an S&P 500 ETF in the stock market (historical 10% return).

-Master lease option now, with option upon TODD actuation or some period afterwards.

So imagine having 8% more total spending power that you never have to pay taxes on since credit card cashback is not taxable per the IRS.

Since there is not a tenant occupying the property, check your termination options.

The project took too long, partly due to the power company taking 3 months to move service and poor communication with the county for permits.
