If you buy a large property (say 100 acres) for $100K, and sell a few small parcels from it totaling 20 acres for $60K overall, do you have to pay any taxes on the sale or would that still be considered non taxable since you haven’t realized a gain over the initial $100K purchase price (even though you still maintain possession of a majority of the land purchased)?

How often is this necessary and how difficult are these to maintain?   

Studying CapEx comes from experience, calling vendors and inquiring about pricing, and from going to the store and looking at costs for building materials.

@Greg Scott I didn’t explain this well, but I would want to maintain this amount consistently - so if I have a repair, I need to get back to $15k.

It's an older lady and she's not too savvy.There are some Owners that will act as a bank, and let you purchase property - you would be in charge of maintaining the property as well.  

I have both newer and older construction properties and I can personally tell you that the older the property the more expensive it’s going to be to maintain.

My thought is you want more owners than investors for long term appreciation, but not sure I've ever seen a study on this. 

You are legally required to maintain essential aspects of the property in good working order.

I have been (and am) studying vigorously and am ready to put my action to work.
