Help! purchase single fam home with 8 acres for subdivide

[Carlos Rosado]

Hi,
I am interested in purchasing a single family home with 8 acres in Orlando close to where I live.

My idea is to subdivide this lot as follows
------------
current house -> 1/4-1/2 acre road frontage, keep as rental

1 acre lot -> build 3-4 unit townhouse (1600+ sq ft each) for rental units and/or RV/boat storage

keep the rest of the parcel to build my own property in the future.
-----------
I know these types of lot subdivisions are allowed as the lot left of it is exactly divided this way (3 way, front, middle, back with 3 narrow driveways)

Now the asking price of this property is $328k. I am positive a $285k offer would be strongly considered.

My main question is.. how can I finance this? I first thought of a regular second property/rental mortgage and the single family home already there (vs. raw land) would facilitate this but then I would be locked in for any subdivision of the lot or new construction until this loan is paid off correct?

Can I just get normal income property loan and once I am ready to build the rental units request one BIG construction loan to pay off the first, subdivide the lot, and build the townhouses?

I am slightly flexible on where I can live so I can just request a primary home loan for better rates, rent my current home, move in to the existing house and then move again to one of the townhouses until I build the last primary property.

Any creative ideas to make this work? I really love this piece of land and would like to make it of my own.

thanks a bunch
Carlos
