@John Kelleyreally depends on exact location, current zoning, what type of demand generators in the area, what’s around it etc...lots of questions to determine highest and best use.

It is half of my grandparents original estate that's been in the family for generations.

It's a trope, but real estate is a relationship business that compounds on itself as you generate more and more happy customers.So keep your job and save up for that 6 months' savings that @Gregory Schwartz called out - that's a pretty standard figure for about how long it takes to see any sort of money coming in. 

The cost of constructing an additional 7 units is between $1.3-1.4M and would generate a projected $118,000 annual rent for a total of $210,000. 

How are you setting up your website to generate leads in multiple markets?

I work full time as an electrical fitter , and my goal is to build my property portfolio over time and generate enough cashflow to match my income .

@Karthik RamachandranWholesale your deal, and then some to generate enough cash so that when you have your next $7M you can buy it yourself. 

I'm assuming this will be some portion of the cashflow the property generates.

I know the AirBNB property would generate more income on a monthly basis but it fluctuates.

If driving for dollars is your main source for lead generation how many hours a day are you driving?
