Rental prices are expected to keep rising into 2022 following the already high-rental price spike of 2021.

The cause of pandemic-fueld price hikes for tenants is due to a combination of factors, which include rising home prices, a shortage of available homes, rental properties growing scarce, and low rental-home vacancies.

Rental data blog Zumper released its annual rent report on Wednesday, and the figures were staggering. The report showed that in 2021 there was an 11.6% rise in the median one-bedroom unit, while two-bedroom units jumped 13.6%.

Such a jump might suggest a looming correction but that's not the case. The same reasons rent jumped in 2021 are likely to keep rents climbing in 2022.

“High home prices, low inventory, fierce competition among tenants and the fallout from the pandemic are having major effects on home rental prices. For renters, that means finding a home to rent may take some time and rent increases will stick around for the rest of the year and into 2022,” a report in noted.

According to data from Zillow in August, rent was up 11.5% from a year earlier, or almost $200. The median rent price in the U.S. in August 2020 was around $1,530, which jumped to around $1,739.

The rent spike has also been dramatic because median rent prices had never gone negative in 2020 -- they just stopped increasing as much.

Financial Samurai noted that even if rent does pull back in 2022 from its fast-paced growth, rates will still be on the rise.

“If median rent price growth is really about 11.5% [year over year in the second half of 2021], I suspect median rent price growth will slow to about 6% by the end of 2022. That’s still an 18.2% increase in rents in two years,” Financial Samurai predicted.

Mark Zandi of Moody’s Analytics told CNBC that he believes that the major changes to the housing market have to do with the extra money that has been given out in stimulus checks and it's now finding its way into rent prices.

“There’s a lot of evidence that the lack of housing closer to where the demand is and urban cores is having a meaningful negative consequence on long-term economic growth," Zandi said.
