Some landlords pointed out that to set up a trust, you usually need to hire an attorney, declare a trustee, and all that stuff - not that big a deal for a 100-unit apartment complex, but a bigger deal if you only own a couple of single-family houses. 

My mother in law lived across the street where it happened, owner had to sell because the rooming house was declared illegal.

Recently the association for this complex changed and I cannot get hold of the owner or association regarding this issue to see the new declaration.

So, you aren't declaring what you own because he figures CA can't find out?

The main reason for putting my property in a LLC is so that I don't have to declare the rental income on my own income.

All contracts, options, or other devices not based upon a substantial consideration, or that are otherwise employed to permit an unlicensed person to sell, lease, or let real estate, the beneficial title to which has not, in good faith, passed to such party for a substantial consideration, are hereby declared void and ineffective in all cases, suits, or proceedings had or taken under this chapter; however, this section shall not apply to irrevocable gifts, to unconditional contracts to purchase, or to options based upon a substantial consideration actually paid and not subject to any agreements to return or right of return reserved.

-If we declare we do want to renew the ground lease, the owner of the underlying land has the right to buy us out of that option for the value of any improvements on the property (i.e. the warehouse and any other improvements) for the assessed value of those structures.

Otherwise I will manage the property and flex new business muscles.

However if they are causing other issues as in your case, I would notify them of the Florida legal limit of 2 residents per bedroom (6 people in each unit in your case), and then give them a chance to declare any residents not previously listed to the lease, up to that limit, with the others having to move out.

2) If tenant pays holding deposit, signs lease well in advance of move in date, and then never moves in/pays rent, can language be put in the lease that voids the lease in this scenario or would I still need to go through the formalities of eviction/declaring the property abandoned?
