Any advice?

I am a student working on a degree in programming. I have to do a case study and I elected to create a program for a friend who has a real estate business. She is still doing business the pen and paper way, but thinks she may be losing money on some of her properties.

I had to create a basic hotel app in a previous VB class, so I decided to start there. I have already created the MDI with a form that will add new rentals as she buys them (she occasionally buys a new property), and store basic information about each rental in a SQL Server database. I would like to create a second windows form that is capable of storing each transaction made for each rental property. In other words, I want to be able to select a rental property and see each time the tenant paid rent or money was spent on a repair (credits & debits).

What would be the easiest way to accomplish this?

I was thinking of somehow coding the program where every time a new rental property is added, a new table is created automatically. Then have a combo box that allows the user to select which property they want to see, and the form applies the correct table adapter based on the user's selection. Is this possible? And, if so, how would I code it? Or is there an easier way?

Thanks!
