However, my wife and daughter are not keen on moving, so I believe my best option is to save and proceed that way.

The husband proceeded to argue with us that they were there on a month to month basis.

What kind of expenses can be claimed back from the sale proceeds?

If you're concerned with interest, you could do a consolidation exchange and  purchase fewer properties for cash using the proceeds of several old properties sold for cash  without taking out a loan and let those work for you till interest rates are in your favor.  

If you don’t have the right temperament and sufficient cash reserves, you should consider selling the property and investing proceeds in passive type investments. 

Would I be able to take my proceeds and 1031 them into a different asset outside of the entity (that owns the rental)?

It appears you are planning to Proceed with caution which would be my advice.  

and I will not just rely on 'the apps' - paying the title company as needed for a title report of course before proceeding with deals.

Or people use a hard money lender who do still require a down payment but they use a partner's money who is getting a split of the proceeds of course.

He then proceeds to say the tenants upstairs have 'destroyed' that apartment and it will need to be gutted when they leave, hey says they are filthy and have brought in roaches.
