So far, I've been looking at properties near the area I'm looking to buy that are listed on Airbnb and VRBO to see what the average rents look like, then taking those nightly numbers and multiplying by 200 (thinking that's a reasonable guess on how many nights a place is rented within 5-10 minutes of the Gulf in the St.

whats wrong with using a Gross Rent Multiplier? 

With 25% down you get a 4x multiplier on returns. 

Possibly calculating the percentage of rental income to all income and multiplying that by the total state tax paid.

Your best bet would be to run a profit and loss for example and export it to excel and multiply all the numbers by 50%. 

Now multiply that by X mobile homes, all of them flushing things they shouldn't be flushing, and that's that.

The assessed value is then Multiplied by the Equalization factor which is 3.2234. then the equalized assessed value will be multiplied by the assigned tax rate for the Municipality/Property.

$80k rehab is pretty huge. gonna be alot of investors that wont want to get in that deep, or dont have the funds to allow them to.not sure if the correct property was linked, it shows asking price of $38k.If it was a wonderful deal, which im not saying this is or isnt, posting a link to the info isnt smart, anyone can read these public forums, not sure how well this property is advertised or not, but if you do all the dirty work to find these properties, I personally wouldnt want everyone knowing the street the property is on and other info.3300 in rents, using 50x rent multiplier, $165k would be a decent purchase price.

I would also argue that the assets / equity (equity multiplier) is lower for rehabs because more equity is required on less favorable terms.

Multiply that by several dozen rentals and the result is significant.While reading your posts for over a year, my mouth has sat agape to see how much money was invested and how hard some of you have worked to get a measly $100 a month!!!
