There are a lot of site-specific issues you need to investigate before deciding what the land is worth to you.

Something a couple of my beginner investors like to do is live in the property for a year or two then move into the next one and rent out the first one.Most important thing you can do is research the different niches within real estate investing and decide what fits best for you.

So I've been getting into real estate and found out about wholesaling and I'm 16, I've been studying and taking notes about the fundamentals and basics of wholesaling, I've decided to start saving up till I'm 18 for when I start wholesaling to be prepared.

You already decided what it is you "should" be doing, while simultaneously stating you don't know what you should be doing.....

I am left feeling that working with them was a wasted investment and decided to cut my losses and move on. 

But you have the option to just pay the monthly payment up to maturity in case something goes wrong or if you decide you can use that money better to just build another property instead of paying it off. 

Well anyone can write anything into a contract, but whether it is legal and enforceable is for the courts to decide...It is State law here that a contractor must call 811 or they are liable for the costs.

This is the point that I would get to before deciding what would be best for my plan and my family.

If the eviction goes to court, then there is a record of that eviction on their file and it will make it harder for them to find another place to live (assuming the landlord does a background check).Not renewing the lease happens when either party decides they simply don't want to renew the lease. 

I'd decide what is reasonable in the market that you want to invest in and create a strategy around that- not what a stranger (who, very likely has never done a deal) says on the internet.Best of luck- happy investing!
