Buying or selling a home is one of the most significant purchases/sales you will make in your life. A real estate lawyer can help you avoid common problems, explain/revise standard forms such as extensive purchase agreements, and explain tax consequences of the transaction. Even if you don't think you need a lawyer for negotiations, they can serve as a resource on your side to walk you through the small but important details.
Sellers typically have to think about real estate agent commission, loan payoff costs, transfer taxes, and title insurance fees. Buyers typically need to consider the down payment, home inspection, closing costs, and cash reserves.
A will is a legal document that states how your properties and assets will be distributed if you pass away. As soon as you get married, have kids, or start to accumulate assets it is important to get a will.
The major requirements for making a will are being a mentally competent legal adult, and having it signed by yourself in the presence of two valid, disinterested witnesses. The document also must clearly state your intention to use the document as your will.
