I am considering investing in or near Orlando, Florida, in a Single Family Property, below the median in a high demand area where there are lots of people moving to.

I moved from Florida to start investing in Columbus due to the same reason.https://www.zillow.com/learn/hottest-housing-markets-2024/

Here is what numbers look like when I move out: Negative cash flow but1.

No value add was needed, I did toy with the idea of moving a mobile home to the property.

U want your parents to talk to their CPA FIRST.. if they go the development route they are now ( depending on the amount of units) creating inventory.. which will be taxed at ordinary income rates ( very HIGH)if they just sell they can 1031  and move on to something else.. many times when you run the math consider the risks of a partnership.. the sale of the land is far better than thinking your going to make some profit.. 

Quote from @Conte Cuttino: My advice is very basic: always hold a property unless you can sell and invest the money in something that provides a greater return or moves you closer to your goals.

(can't remodel until tenants move and they typically stay for several years)  Also have new signage coming.

If the property owner is a "long time childhood friend", then she may be willing to cut you a deal where she pays for the closing costs and/or she may contribute to any repair/remodeling work that the property may need.Once you move in you could house hack and start saving money so that you can acquire more properties. 

Especially with me having serious buyers and feel as if I could move the property fast.
