Before you fall for a room, write four numbers on a card: the price people are asking, the rent similar homes actually get, a yearly repair guess, and how many months it might sit empty. If you cannot find a rent that is real, you do not have a deal. You have a daydream with floorboards.
This class will not tell you to buy. Rules, taxes, and lending differ by place, and a licensed person should see any real offer. The card is a filter so weak ideas leave early, while looking is still cheap.
A pretend example. Pretend a porch is listed at 240,000. Nearby rent looks like 1,500 a month. Repairs get a first guess of 2,400 a year. Empty months: one. Those four numbers are enough to keep going or to walk away before the open house cookies.
