Today’s economy has become rather shaky since the real estate market bust. With people losing job security and job creation moving at a slow pace, it is understandable to want to have investments that will churn out income even if one does not have a job.

Though the real estate market is only starting to pick up, it does have investments related to it that one might consider getting into even if you don’t have wads of cash to spend: tax liens. But before jumping the gun, below are three must-knows in tax liens investing:

Understand Interest

When investing, it is important to know just how much return of investment is to be expected. Purchasing property tax certificates guarantees a fixed return of as much as 50%, especially when a tax-defaulted paper was bought from a particular state. Though there are states that give less than 50%, real property can usually be counted on to make investments secure. However, many states have complicated rules about how interest is paid on tax liens, so make sure you understand all the in’s and out’s of your particular area’s interest rules, rates and regulations before you bid.

Do Not Rule Out Risk

Investments do come with risks. Period. The question now is, just how much risk are you getting yourself into by investing in tax liens? Most tax lien investors prefer not to invest in properties controlled by the Federal Deposit Insurance Corporation (FDIC) and influenced by the Drug Enforcement Administration (DEA); these associations can increase the chances that your property investment will not pay off. Make sure that before investing, you conduct investigation so as to reduce the possibility of loss.

Know Where to Invest

There are some counties that sell more tax liens than others. This can be due to a number of factors, including ease of redemption, investing laws and interest rates. The largest U.S. County to sell Tax Certificates is Maricopa County in Arizona. Online resources make it easier for the county treasurer, assessor, and recorder to research tax liens properties. You will have to determine what area of the country is best for your personal tax lien investing needs and preferences before you get started.
