My payment increased $1200 per month.

But, buy, but ,but but....each to their own.You can not increase cash flow with cash.

Refinance at the start of Year 2; $185k ARV * .7 = $129,500 - $50k balloon = $79,500 + $12,744 [cash flow from rent with new mortgage] = $92,244 cash flow Year 2Sell in Year 5; less the balance due on the amortization schedule $121,909 = $63,091 cash flow Year 5The present value is now $135k which means that if I put in $140k at the start ($80k purchase price + $60k rehab costs) I overpaid by $5k.I realize there are a lot of limitations to this, for starters I didn't increase the rent at all and I assumed no appreciation beyond the ARV.

For my portfolio, we always do an increase of 2-5% to keep up with the increase in property taxes (2% on average year over year) and the market increase (somewhere between 5-10% in my area).

Depreciation qualifies as a business deduction.You do increase the chance of an audit with an amended return.

Maybe increase your marketing budget, change your content or try a different strategy all together.Unfortunately marketing effectiveness changes rather quickly nowadays.

I love the idea of getting an FHA, 203K loan and immediately fixing up as much as I can right away to immediately increase rental income. 

John, if you don't mind giving a few more moments of your time, with the increased expenditures, how would you adjust the offer to the owner?

I don't have any experienced with Jacksonville, but it appears @Carolyn Morales has provided you some good intel.
