If you are wholesaling, you need to know what your ideal client wants. 

Ideally i would be looking for a small multi family (2-4 unit) or a SFH that i can put some sweat equity into and hold for the long term.I will be heading down September 5th-9th to take a small tour of the areas that I believe I'm interested in.

Converted 3 bay garage into movie theatre and 2 game rooms.

Maybe I could gather some ideas about my next move.. ideally, (I think) at this point I'd like to get myself into a duplex and rent out one of the units.

Current LTV is around 50%, so the LOC would ideally be 65%-70% max LTV at least.  

If you can a detached duplex is ideal option as the rent on the non owner occupied unit will help your income qualification.  

I would like to know how to buy a home that I can realistically afford, ideally in Central Florida – either Volusia County (North of Orlando) or Pasco County (North of Tampa).

The higher taxes aren't ideal of course, but the tenants pay a higher rent and the taxes are accounted for in those rents. 

I find just like you the tenants stay longer and I deal with less nonsense calls and maint issues than I did from my multi family.

Personally, I pay out of my pocket for all of those up front and recognize I am at risk of losing all those funds.If you do not have the cash, you would need to find someone that wants to partner up with you, ideally before you put in an LOI.
