Yes, you can enforce your lease agreement as to the tenant, but unless you require the sub-tenant to use a specific lease agreement, the tenant could use a lease agreement that does not match the way your lease agreement governs the tenancy.

AB1482 says:“This property is not subject to the rent limits imposed by Section 1947.12 of the Civil Code and is not subject to the just cause requirements of Section 1946.2 of the Civil Code.

I am open to properties that may require minimal renovations if the deal aligns with my investment criteria.My long-term plan is to scale my portfolio deliberately, ideally acquiring multiple properties within the next 1-2 years.

I have come across multiple properties - typically houses that require rehab - where the seller is not the owner of the property but what I believe to be a wholesaler or investor who has been assigned the rights of the property to sell to an end buyer (me) for a (substantial) fee. 

Of course, if they don't vacate the premises by the date they are required, you should take the necessary step to terminate the tenancy, whether by a 3 Day Notice to Pay or if they are a holdover, by delivering demand to vacate with notice that they are a holdover and owe double rent per F.S. 83.58.

Not to disagree with Thomas or Jaron, but a question I would have is more to the termination requirements for your jurisdiction. 

The ladder move requires capital.

He has agreed to pay off the taxes owed.I'm not what steps are required for us to move forward. 

If the repair process requires painting the whole thing, which it may need to look good- I'd optimistically put the lifespan of a professional/specialized 2-part (epoxy or urethane) tub/surround (or tile paint) etc- paint job, with above average prep work at ~3 years.. a "high quality" tub respray like this will cost just as much as a brand new tub, and touching up/blending a spot repair is specialized, expensive work as well. but yes I agree with the other replies either way -(unless, *perhaps* there is already easy access from behind etc to get to the repairs and inspect flooring etc without taking tub out)- it makes sense to rip it all out so you can address any potential water damage, and overall there is no reason the resulting new unit shouldn't cost aprox the same ballpark as the repairs .. and new of course will look much better with a much longer lifespan. 

It can be a great strategy especially if you are in a desirable area (which it sounds like you are).
