I also recommend Rich Dad, Poor Dad; Tax-Free Wealth and there are a couple of others that I don't want to bore you with.Good luck. 

This is likely your best bet assuming that seller financing is a thing in the UK.I randomly have a UK lender connection.

The home inspector (highly rated) did not seem to think it was a major concern and seemed to think it may have been a poor job or was done in the summer and dried to quickly.

It was a terrible buy as it's a 40's concrete house, 700sqft, and IMO rehabbing a concrete house isn't worth it due to poor insulation among other things.I have around $60k saved and am frozen on if I should pull the trigger on a deal in OR where prices are super high and use financing to rehab a buy and hold rental, or go out of state where I can buy something for cash and rehab that for a buy and hold rental. 

Best bet is to just keep renting it for the next four months and refinance then.

That would be your best bet for cash flow. 

This will continue until the property is paid off and the ROE will continue to go down.If you want security, but we see that paying off the property is a poor use of funds, what else can we do?

You will want to dig into why they are below market -- lazy seller, poor unit condition, high supply of units, etc.

As you probably know, a tenant cannot remove items that are attached or fastened to the building....like sinks and ceiling fans....that is unless they had them installed themselves...But as @Glenna Wood said, it's probably not worth bothering to go after a tenant like this....just lick your wounds and move forward.I bet you screen the heck out of the next one, eh?
