The property owner has a set amount of time to pay their delinquent taxes (redemption period), if they do not, you can take ownership of the property.A tax deed is where you buy the property directly from the county and take ownership right away.Please check specifics for FL.Either way you are "taking care of the taxes" and would not need to "pay the owner" anything. 

Do you contact people by mail, finding distressed buyers would make the most sense, there's plenty of pre-foreclosures.I'd probably shoot for a BRRRR, most likely a buy and hold for 5 years flip while renting, I'll be living in the property since I only have FHA(3.5% down) / Rural financing (0% down) / Home Ready (3% down) loans I'm clearly very hesitant about the Utah market because it's so overpriced, but people are still buying so maybe I just don't know something.Side Note* I was looking for a rundown shabby home in the sugarhouse / U of U area because I rented in that area for a period of time and Google Fiber is honestly amazing and Comcast internet sucks. :)I use rental property calc for a lot of my calculations should I only care of the IRR if the cash-flow is Negative?

Its particularly tricky if you take a rental out of service for a prolong period, then rent it out again.

I guess I’ll just set my expectations to a 4-month grace period before I start following up.

I think these are way less scary than the pier and beam variety, but maybe that is just me.You then have to let the house settle for some period of time before you really set about your renovations, but you can still use the time to rip out old stuff, get your materials ordered, and gather bids from contractors - all things you'll need to do anyway.

Agree with Adam, and that fee assumes clean and reconciled financials are provided (trial balance, profit & loss, balance sheet, and general ledger in Excel format).Partnerships are anything but simple now. 

Are there any drawbacks to refinancing twice in a short period besides the additional closing costs? 

I don't think the waiting period that most lenders require is a secret.

Call an agent and get a quote, don't guess at it or take the word of some moron like me off the interwebs :) Taxes are easy enough to look up and you're paying taxes on the land and building, I don't believe there are commercial or residential taxes, just property taxes period, but I could be wrong...so look them up online or call the city. 

All of this will be from real estate sales with a holding period of longer than a year, as the development and sale will last past 12 months.
