That’s expensive and time consuming. 

I know certain things like insurance, etc. can't be deducted.Are there are big missteps I should make sure I'm not making in my assumptions/landmines I shouldn't step on to make sure I can deduct these expenses and receive the right rebates in my tax returns at the end of the year?

Expenses can eat up profits in less expensive areas. 

Since it’s a single-member LLC, the IRS disregards it as a separate tax entity, which means there typically aren’t any capital gains or other tax consequences when moving the property to your personal name.However, keep in mind that if you have financed the property, transferring it may impact the loan terms, and expenses like interest and property taxes might not significantly affect your overall tax situation.

(Miami is an expensive market too.)

Am I a fool not taking the mileage expense?

From what I have seen rates can be very expensive and the advice can be too general.

If you're in midtown/east Memphis where it's a more expensive area that can be a little more modern/trendy I don't think a horizontal fence would be a bad idea.

Zillow is trying to make more money from a lower amount of leads, this is not even the most expensive I've seen.

These expenses would lower your taxable income and further reduce your overall tax liability.
