One Landlord Lost $7,550 Chasing an Extra $150
A case study on market data, tenant retention, and the true cost of vacancy.
Every landlord wants to maximize their rental income. It’s a reasonable goal since rental properties are investments, and investments should perform. But there’s a critical difference between maximizing rent and optimizing it. One leads to long-term returns. The other can quietly cost you thousands.
This is the story of one of our managed properties in the summer of 2025, and a decision that turned a thriving tenancy into a 61-day vacancy, and over $7,000 in expenses.
The Setup
In July 2025, we were managing a single-family home leased at $2,150 per month to a reliable, established tenant. As the lease renewal window approached, we conducted our standard market analysis pulling comparable active rentals, recently leased properties, and absorption trends in the area.
Our conclusion: the market did not support a rent increase. In fact, the open market rate was running $100 to $150 below what the tenant was already paying. Our recommendation was straightforward, don’t increase rent, preserve the tenancy, and protect the investment.
The owner disagreed and questioned if we were, “Working for the tenants“, a common example of how emotional decisions can impact rental property performance.
The Zillow Problem
The owner had been browsing Zillow and spotted listings asking $2,300 per month. He wanted to raise the rent to match what he saw online, reasoning that if other landlords were asking for it, he should too.
This is one of the most common, and costly, misconceptions we encounter.
Listing prices are not lease prices. Zillow shows what landlords are asking, not what tenants are actually paying. A listing sitting at $2,300 for 45 days with no takers isn’t evidence of market strength but rather evidence of a price the market has already rejected. Real market data comes from signed leases, not active listings.
We made the case clearly, laid out the lease prices for those properties that rented in the last 90 days, and the prices those new tenants were willing to pay. We showed how properties that were listed where he wanted to did not rent at that price, but rather had multiple price reductions, experienced multiple month vacancies, before ultimately renting below his current market rate. These tenants, who were already paying above market, but did not want to move to only save $50-$100. The risk of turnover was real. In short - the data didn’t support the increase.
What Happened Next
The tenant declined the new rate and informed us they would be moving out when their lease expired.
The owner, who had been weighing a potential sale, listed the home for sale on September 1, 2025, despite the tenants not moving out until September 30, 2025. The property did not sell.
After the listing failed to gain traction on the sales market, the owner pivoted back to the rental market. It finally leased again on November 29, 2025, at $2,200 per month.
That’s 61 days of vacancy. And a final rent that was only $50 more than what the tenant had been paying before.
Running the Numbers
Here’s exactly what this decision cost, no estimates, no hypotheticals. Real numbers.
| Loss Category | Amount |
|---|---|
| Lost rental revenue (61 days vacant) | $4,372 |
| Unit turn costs (cleaning & repairs) | $1,150 |
| New leasing fee (new realtor) | $2,200 |
| Carrying costs — mortgage + utilities ($2,100/mo × 2 months) | $4,200 |
| Total out-of-pocket loss | $7,550 |
At the current rate of $2,150, that is a daily rate of $72. Even if he had a realistic probability of achieving the additional $150 a month, he would have to rent the property in under 25 days to be net positive, and that is assuming no unit turn costs. That is also not factoring the “known vs unknown” when it comes to the tenant quality.
So what did he gain? The new lease came in at $2,200/month…just $50 more than what the tenants he pushed out had been paying. The rent increase he was chasing was $150/month, or $1,800 per year, despite the marketing screaming at him that he was not going to achieve that rate.
He spent $7,550 to chase $1,800.
Meanwhile, the original tenant would have renewed. No vacancy. No turnover. No leasing fee. No out-of-pocket carrying costs. This is why strong tenant renewals are often one of the most valuable drivers of long-term rental returns.
The Lesson for Landlords
We’re not sharing this to be critical of the owner as decisions like this happen every day, and the logic seems sound on the surface. If the market is asking $2,300, why settle for $2,150?
But the market wasn’t actually getting $2,300.
Effective property management isn’t about pushing rents to their theoretical ceiling. It’s about reading real data, understanding tenant behavior, and calculating the full cost of decisions, including the cost of being wrong.
Vacancy is the single greatest threat to rental returns. Two months of carrying costs alone, mortgage, utilities, maintenance and upkeep, wiped out more than two years worth of cash flow.
If you’re self-managing your rental or working with a manager who doesn’t provide market-backed renewal recommendations, this case study is worth reviewing.
The best rent isn’t always the highest rent. Sometimes, it’s the one that keeps a good tenant in place and your investment performing.

Frequently Asked Questions
1. How do I know if I should raise the rent on my rental property?
The decision should be based on actual market lease data, not just asking prices on rental websites. A professional rental market analysis compares recently leased properties, current competition, tenant demand, and your property's condition. In many cases, keeping a reliable tenant at market rent delivers a better long-term return than risking vacancy for a small rent increase.
2. What is the true cost of raising rent too much?
The cost of raising rent isn't limited to losing a tenant. It can also include vacancy, cleaning and repair expenses, leasing commissions, mortgage payments, utilities, and the uncertainty of finding another qualified resident. As this case study demonstrates, chasing an additional $150 per month resulted in more than $7,500 in losses after a 61-day vacancy.
3. Should I use Zillow to determine my rental price?
Zillow can be helpful for seeing what properties are listed for, but listing prices are not the same as leased prices. Many rentals sit on the market for weeks before reducing their asking rent. The most accurate pricing decisions come from recently leased comparable properties and local market data that reflects what tenants are actually willing to pay.
4. Why is tenant retention so important for maximizing ROI?
Keeping a qualified, reliable tenant often produces higher long-term returns than frequently increasing rent. Every turnover comes with costs—including vacancy, maintenance, cleaning, marketing, leasing fees, and the risk of placing an unknown tenant. Reducing turnover is one of the most effective ways to improve your property's overall profitability.
