Rent vs. Buy in Renton: What Rates Above 7% Do to the Math

What Renting Costs in Renton

I run this math for Renton renters all the time. Here is the honest version, starting with rent.

Zillow’s rental data puts the average Renton rent at about $2,500 a month across all home types, as of October 22, 2026. By size, Zillow shows about $1,660 for a 1-bedroom, $2,150 for a 2-bedroom, and $2,950 for a 3-bedroom. RentCafe, which tracks larger apartment buildings, shows a citywide average of $2,165, with 2-bedrooms at $2,290 and 3-bedrooms at $2,758 as of October 1. The two sources measure different things, but they tell the same story. A 2-bedroom runs a bit over $2,100 to $2,300. A 3-bedroom runs about $2,750 to $2,950.

What Buying Costs in Renton

Now the other side. I keep condos and single-family homes apart, because a blended number hides the real choice.

Renton, 20% down at 7.35% Condo Single-family
Median price, 12 months through September $362,500 (down 7.8%) $781,950 (down 4.3%)
Down payment (20%) $72,500 $156,390
Principal and interest $1,998 $4,310
Property tax, estimated about $311 about $671
Monthly, before insurance and HOA about $2,309 about $4,981
Comparable rent (Zillow average) 2-bedroom: $2,150 3-bedroom: $2,950

Sources: NWMLS monthly data through September 2026. Mortgage News Daily 30-year fixed, 7.35% on October 28, 2026. Property tax estimated at Renton’s median effective rate of 1.03% (Ownwell, April 2026). Rent from Zillow Rentals, October 22, 2026.

The condo is close. At about $2,309 a month, it costs about $160 more than the average 2-bedroom rent before HOA dues and insurance. Add those, and the gap grows to a few hundred dollars. Dues vary a lot by building, so the real gap depends on the condo. The house is not close. At about $4,981 a month before insurance, it costs about $2,000 more than renting a 3-bedroom.

What Buying Gets You That Renting Doesn’t

Part of each mortgage payment pays down your loan. On the median condo, about $2,753 of the first year’s payments goes to principal. That is money you keep, not money you spend. The share grows every year.

Your payment also stays put. With a fixed-rate loan, principal and interest do not change for 30 years. Rent usually does. And if rates fall later, you may be able to refinance. Nobody can promise that, so do the math at today’s rate and treat a lower rate as a bonus.

Renton buyers also have more room to negotiate than they have had in years. Renton had 344 single-family homes for sale in September, up 73% from a year ago. Homes took a median of 30 days to sell, and sellers got 95.5% of their original price. In the last four weeks, about 30% of Renton single-family sales included seller concessions. A credit toward closing costs or a rate buydown can change the monthly math. My post on rate buydowns shows how that works.

When Renting Still Makes Sense

Renting wins if you might move within a few years. Buying and selling both cost money. My guide to buyer closing costs shows the buy side. If you sell in two years, those costs can eat whatever equity you built.

Renting also wins if the down payment would empty your savings. A home needs a cushion for repairs, and a condo can bring a special assessment. If you want to buy with less than 20% down, look at the down payment assistance programs and my FHA vs. conventional guide. A smaller down payment means a bigger monthly payment, so run both.

My rule of thumb: if you plan to stay five years or more and the payment fits with room to spare, buying a Renton condo deserves a serious look. If you want a house, the gap is large right now, and renting while you save is a fair call. My income needed to buy in Renton post shows what lenders look for.
