The thing you want to avoid happening is the IRS deeming you that you live in multiple places and your travel then potentially becomes non-deductible(depending if you do have a business).Items such as registering for a new state ID, paying for utilities, applying for state voting, etc help establish your new tax home.

Therefore, you will want to confirm that the trust company allows for investing in an LLC and the associated fees and minimum balance that applies to the IRA account.2.

The other thing that may apply to you in FL, that sometimes happens in CA is a property not having an AC system if it is close to the coast, probably less relevant given the humidity in FL but I thought it was worth mentioning.

I did some digging and it looks like the new law doesn't apply to “owner-occupied properties with three or fewer units, owner-occupied single-family homes." 

@Parag Doshi the 2% rule doesn't work in most areas at this point in time, many investors have moved to the 1% rule, but the problem with both is that they are too broad and people try to apply them nationwide with no regard for the intricacies of a particular market. 

@Andrew Aladjadjian is correct re the new owner occupancy law, I would just warn that I have a few clients who built ADU's in LA (SFR) and now the cities rent stabilization unit is trying to call it a multiunit and apply rent control to their single family homes. 

1) It is not yet clear but it seems that you will be grandfathered in at the time when the changes occur in regards to occupancy changes.2) Per AB-68:"(A) One accessory dwelling unit and one junior accessory dwelling unit per lot with a proposed or existing single-family dwelling if all of the following apply:(i) The accessory dwelling unit or junior accessory dwelling unit is within the proposed space of a single-family dwelling or existing space of a single-family dwelling or accessory structure and may include an expansion of not more than 150 square feet beyond the same physical dimensions as the existing accessory structure.

If they have over paid that can be applied as a credit against future Additional Fees. 

I've found the same advice applies to tenants and PMs "if you think you need to end the relationship, then you need to end the relationship". 

Curious if anyone has ever applied for a rooming house license?
