I would think their loan documents give them the right to control the property after the original owner dies - regardless of who is living there (although I have no direct knowledge of the laws where you live).There are details we don't know here... like if you want the house for sentimental reasons, or because you see the value between what it's worth on the market today and what the reverse mortgage company wants for it?  

First, what does your lease say about pest/rodent control? 

During that time the property had appreciated significantly and the seller was attempting a "shake down" to regain the property or get the appreciation, which he lost.

On 60k of lost rent they collected exactly zero.

Just a few hours of preparation could have saved you many hours of effort, a lot of worry, and thousands in lost income.

.- Ask attorney how you can enforce collecting on the lien when you need to.3) Getting full control of the property, while allowing your aunt to keep her ownership.- Have attorney draw up a contract to do this.Suggest you offer your dad some cash, now or in the near future, to motivate him to transfer his ownership to you.It may not work out, but you will learn a lot either way!

I don't see a national rent control law ever coming into law - aside from the fact that there's just no need for it, there's way too many things working against it - Congress, constitutional law, lobbyists, etc.

If there was no appreciation, there is no need to do a 1031 exchange.I have never been a fan of condo's as you lose some control over the investment - You have no control over the monthly maintenance fees, you may not have control over who is on the board, you have no control over special assessments.I wish the investments turn out well for you!

So if you paid 3x the price of the previous owner, and lost the homestead exemption due to using it as an investment property, it is entirely feasible for taxes to double or triple.  

These typically include services like renters insurance, HVAC filter delivery, pest control, and sometimes utility management.
