Basically the building size is limited by the lot size. 

I am looking at a property that has a garden level/basement with ~7ft ceilings, normal height/size windows, and 2 separate ground level entrances/exits... it backs onto a hill and is roughly 80% above grade. 

Costs like engineering and permitting can become disproportionately high for mid-size projects.Height and Density: Focus on areas where zoning allows for verticality and density.

These are all STR communities that have similar amenities, close to Disney and have various sized homes that do well in the STR space.

I'd recommend getting multiple quotes from service providers to see what pricing is going to look like per square footage.Without too much information provided and depending on the size of your home it could be anywhere from $5,000-$15,000+

With the funds you listed and property size you should be able to comfortably have 2 even 3 projects going at once (depending on what you're up for), especially after you sell the current house you are renovating.

You're 4x our size, so always looking to learn! 

I’m not trying to rain on anything here but the reality is that measuring Btus delivered to individual units via airflow is by its very nature imprecise - if you want to know why, read on...The size and length of the ductwork is but one factor ( of many) that will yield energy losses while that warm air is being moved to your units.

Most of these failed deals are being given back to the banks or bid at auction but the average size of these deals is 8 figures.
