This sounds just awful. Although it may be difficult for you to pursue a case against the caregiver, it is probably worth contacting a local attorney for some guidance. Gather up everything you have, organize it chronologically and take it to a lawyer for review.
You should consult with a local Personal Injury Attorney right away. The Statue of Limitations on your action is running and soon you will not have the option to file a complaint. Most PI Attorneys will not charge you for an initial consultation.
First you should contact him in writing and make sure that you provide him with your new address. This will set in motion a thirty (30) day window for him to return the security deposit. If he fails to do so, you can file suit (i.e. sue him) for two (2) times the actual deposit. Such a law suit can be started by filing a Complaint with your local District Magistrate. The process is relatively straight forward and you are not required to hire an attorney to do this.
This sounds like a case of a landlord helping him/herself to personal property in an attempt to offset some alleged damage. This is considered "self-help" and that is an action that is not permitted in Pennsylvania. At a minimum, the owner of the property should file a complaint with the local Magisterial District Judge (so long as the damages are for $8,000 or less). At the maximum, this may be a criminal matter and the police should be called.
Read your lease very carefully. If the lease does not give you clear guidance on how to proceed, you should contact a local Landlord Tenant Lawyer to help guide you through the eviction process. Under NO circumstances should you exercise "Self Help" (ex. changing the locks, disconnecting utilities, etc.).
Your landlord may not have a legal obligation to provide you with a copy of the lease, however her statement that "legally she can't give you a copy" is just plain wrong. There is NO law stating that a landlord is prohibited from giving a copy of the lease to the tenant.
Inheritances in Pennsylvania are first and foremost controlled by the Will of the Testator (i.e. someone writing a Will) can disinherit (i.e. give nothing to) anyone they want, except their spouse. If a spouse is disinherited (i.e. left nothing) that surviving spouse can "take against the Will" an amount equal to 1/3 of the Estate.
To answer your first question, yes, you will have to pay Realty Transfer Tax on this transfer of real estate. The tax would be assessed on your entire share of the property (i.e. 1/2 of the total fair market value).
In response to your second question, yes, there are plenty of other things to think about. A couple of them are:
1. Your LLC will be subject to a Capital Stock Tax however if you set up a General Partnership, with the LLC as the General Partner, you could get the same...
I agree. Yes, it can be done, but using a Landlord-Tenant lawyer would be strongly advised. Also, in Pennsylvania, there is a distinction between "ejectment" and "eviction". Make sure you are pursuing the correct type of action.
