It may not come to that, but since this is your first property I would suggest you go through an attorney anyway, even if it's month to month and it just comes down to sending the notice of termination.When I take over a building I also send or deliver a standard "takeover" or "welcome" letter to introduce myself as property manager and let the tenants know the answers to their two main questions: 1) who do I call/contact when I have a maintenance/repair request, and 2) how/where do I pay rent.Then (if the letters were mailed or delivered without meeting the tenants), I follow it up with an in-person meeting to introduce myself and answer any questions they may have.Usually the main question they have, whether they ask it or not, is whether I plan to raise the rent.

Although is fine to deliver a clean, functional  property and no more but  the OP wanted to do more on move in, my thought is link it to the property. 

I used to deliver pizza through this neighborhood literally everyday for years and years.

However I did find last night that the estate owes back taxes for 2018 and that mail is still being delivered to the property which means someone is checking the mail.

They typically appreciate in value, they deliver rental income, and they are always in demand.

In New York, the landlord cannot legally hand deliver or serve his/her own tenants; this must be done by a process server whom is not a party to the contract being breached. 

Should an audit occur, you need the firm to stand behind and defend you by then delivering the asset detail to support the conclusions. 

Id have it delivered by constable too, so you have proof.

Due diligence in checking references and seeing the type of work product each contractor can deliver may take more time at first, but once you have established relationships with the right people, you will save time and money.Budgeting BlundersOn television, property flippers take a quick tour through the property, throw out some numbers, and get to work.
