So, you need to be sure it makes sense as it does not always do so.Also, keep in mind, line of credit are for short term cash needs NOT long term for example a down payment on a property you plan on keeping for the long term. In

We need more energy for data centers (already an issue) and we need much more capable batteries for robots.If a robot is flipping burgers you can just keep it stationary and plugged in, but if you want a robot to move around on a construction site and build a home you need freedom from the cord and a lot of power to lift heavy objects.

Can I terminate the lease and pay him back?

@Tom ThomsonI am not an attorney but my 2 cents is he does not have to return your earnest money in my opinion if he can still meet the closing date on the propertyI view it as you are terminating the agreement because you don’t like the house anymore

Also one allowing you to review the documents (rent roll, P and L, Tax returns, insurance claims history, 3rd party agreements, leases) which allows you to terminate the contract if you are not satisfied.

When I followed up and asked for a specific reason (thinking it might require an additional payment towards principle to put me under the threshold) they wrote back informing me that investment properties do not qualify for automatic termination and that PMI will remain for the life of the loan and if I want to remove it I can look into refinancing. 

These are easy to simply plug in and have a battery backup.$899 XGIMI 4k Horizon Pro Projector - https://www.amazon.com/gp/aw/d/B0967XXVH2Ok so this is pretty specialized but it is 47% off.

I looked at GPS tracking, but they need batteries changed frequently, and a monthly fee to be paid like a cell phone bill, any ideas would be greatly appreciated.

If he refuses, terminate his lease and get him out.Change your lease to include a "no smoking" clause.

Personally, I would give them notice of termination and start fresh with a new renter that I've personally selected, using my lease, at my rent rate.
