Right now I'm just looking To flip the land.The property is 14,000 sq/ft with sewer & utilities at the street surrounded by very similar lots & houses in the neighborhood.

I never noticed fire hydrants until I worked with public utilities, now I spot them everywhere and can rattle off the brand and (approximate) age without much difficulty. 

As others have said, it's probably best to utilize your money buying one or two multi-unit buildings. 

@Jon S, most of the issues I've seen boils down to HOA / code enforcement / underestimation of utility usage.  

But above comment is probably right about tragedy of the commons effect on "everyone's laundry area" which can be a cleaning and utility cost issue and even vagrant or misuse issues..

We have a standard contract, utilize the money for a project and then pay it back in 12 months or sooner (like if a flip sells sooner than 12 months).  

Cashflow is the number you come up with after paying the mortgage (PITI) and also accounting for expenses like vacancy, capex, maintainence, utilities and management.

It's incredibly useful, an amazing program to utilize.

If Florida is anything similar to its northern neighbor (Georgia), you can probably build for as low as $60/sf if you're your own GC, if you don't have to spend a fortune on utility hook-ups and if permit costs are relatively low.We build with mid-level finishes in the low-$60s/sf in Atlanta...

It's really hard to get an idea of cost without someone actually going out to bid the job (not knowing the size, location, grading for the lot, whether you need to add curb cuts to enter this new garage from the street or if it's from the alley, routing utilities, etc).
