If inflation kicks in heavy down the road, those with good investment properties might be happy they bought into this market. Only time will tell.
Landlord
Some real estate investors are landlords. They rent or lease the property for a fee. Being a landlord can be hard work because in many instances the tenants destroy part of the property and the landlord has to fix it before renting it again. They also face problems of tenants not paying rent. They incur expenses for upkeep and maintenance of the property as well as insurance costs and property taxes. Not everyone has the personality makeup to be successful as a landlord, but those that do can become wealthy. This method is certainly a tried and true way of making money in real estate.
Property Flippers
Flipping real estate is probably the most risky way to make money with real estate. There are several ways to flip a property including buying a run down property and immediately reselling it to a renovator, renovating it yourself and reselling it for a profit, buying it and reselling it as is for a profit, etc.
Flipping was hot several years back. It was fairly easy to make money, even for a novice. One has to be very savvy to make money as a flipper nowadays. If you are counting on luck and a rising tide, you will probably lose a lot of money.
In property flipping, there is also money making potential for scouts. Basically, a scout is someone who finds deals for investors and sells the information to the investors or gets paid for providing leads to properties that investors close on. Like flipping, this was a good way to make quick money a few years ago. Today, there aren't a lot of people willing to take a chance on what you find.
Contract Holders
Another type of real estate investment involves selling properties on contract and carrying the note. This is a wise option for real estate investors that intend to make money off the property for the long term. Usually, the people that buy this type of property cannot qualify for a mortgage. The owner of the property can sell the property at market price and collect down payments and interest as well. The person who buys a property on contract is responsible for home repairs, upkeep and insurance. If the buyer defaults, the owner can foreclose on the property and sell it again.
