Depending on what your long term goals are, you might be better off investing in a mutual fund.

Will the property reach your ROI and cashflow goals if you have to spend more money than you planned after closing?

Not only will this put more money in your pocket, but depending on your goals, you can paydown the debt far faster with this method.

To put it simply, I have two goals on a BRRRR.

would be glad to find you the right properties to fit with your goals. 

My goal is to purchase a small multi-family (duplex/triplex) or single family home that can be converted into separate living units within 9 months of my work contract ending.

I am hoping this will increase my holdings and reach my financial goals in a shorter time period than residential.

Appreciate your  goals.

if you insurance business is being reported on Schedule C (not in a S-Corp or LLC) this will not however reduce the self-employment taxes you have to pay on the insurance income.A Cost seg is really a play on the time value of money, depending on your goals with the property it may or may not make sense. 

If I invest the 170k with a 30% cash on cash return, I'd reach my FI goal.
