Real estate in La Prairie
What drives rental demand in La Prairie?

How do you calculate the return on a revenue property?

What should you check in the leases before buying a building?
Ask for a copy of every current lease and renewal notice: rent, term, services included, special agreements. Compare the rents with the market in the area and check for vacant units. Leases stay with the building: the buyer takes them on as they are.
