First time BRRR - Help evaluating potential

[Conor Patrick]

Long time lurker, first time poster.

I have been evaluating multi-family properties using the BRRR and other cash-flow calculators. I believe I have found a solid first deal on a duplex, only 2 minutes from my house. Would appreciate everyone's thoughts to make sure I'm not missing anything.

Details:

Southwest Florida

List price: $320,000

Two 2 bed, 1 bath units, approx. 1000 sq. ft each. Additional 400 sq. ft. storage in shed detached from units. Entire property looks to be in great shape and is in a growing area near the beach (1 mile).

Foreclosed in 2016, investor rehabbed one unit to make it turnkey. Other unit is where I see the value add for possible BRRR.

Both units currently rented for $1,350 per month ($2,700 total revenue per month)

For evaluation sake, I calculated that I had to pay full asking price, $3,000 annual taxes, and $2,000 annual insurance.

Self manage the property, 8% vacancy, $100/month maintenance expenses, $100/month Cap ex, and $100 utilities.

$64k down, and another $15k rehab to bring the 2nd unit in line with the 1st.

I come up with cash on cash return of around 9.3%. I believe the ARV will be around $375 - $380, so may not be able to get the entire $79k+ invested into the property back out immediately, but hopefully a decent chunk.

I know the investor that purchased this out of foreclosure is making out on his flip, but I think the economics of the above are sound. Am I forgetting anything?

What type of initial financing for the rehab period should I be discussing with the banks?
