Renting vs. Buying: My 25% Rule for Figuring Out What You Can Actually Afford

I'm tired of hearing "if you're renting, you're throwing away money." It's repeated so often that people stop questioning it, but it's not the full truth. Renting buys you something real: flexibility. No repair bills. No property taxes. The freedom to move if a job or a life change calls for it. 

Owning comes with its own version of "money you don't get back" — mortgage interest, property taxes, insurance, and maintenance that never really stops. In some seasons of life, renting is the smarter move, not the failure move. I don't believe the goal is homeownership at any cost. It's making the wise decision for where you are right now. 

The Real Cost of Owning a Home 

The mortgage payment you see quoted online is the sticker price — not the real cost. When I talk to people about buying, I always tell them to add in: 

• Property taxes 

• Homeowners insurance 

• Maintenance and repairs 

• HOA fees, if they apply 

Here's a rule of thumb I use: budget 1–2% of your home's value per year for upkeep. On a $300,000 home, that's roughly $3,000–$6,000 a year, on top of your mortgage. Skip this step and the "affordable" home you thought you found can turn into a monthly stretch fast. 

How Much House Can You Actually Afford? 

Banks will approve you for more than you should spend — I say that's not a guideline, that's a ceiling built for their risk tolerance, not your peace of mind. My guideline: keep your total housing cost at or below 25% of your take-home pay, not your gross income. 

That 25% leaves you room for saving, giving, everyday life, and the repairs you didn't see coming. Go past it, and you're stretched thin no matter what the bank says you qualify for. 

Get Your Financial Foundation Ready First 

Before you go house hunting, I want you to make sure the rest of your financial house is standing: 

• Emergency fund in place. It's what gets you through the first surprise repair — and there's always a first surprise repair. I learned that the hard way when my air conditioner blew up a week after I bought my first townhouse at 22. 

• A real down payment. Enough to avoid extra costs like PMI (private mortgage insurance), which kicks in when you put down less than 20%. 

• High-interest debt paid down. Buying from a place of financial strength turns a home into a blessing instead of a burden. 

Buy on Your Timeline, Not Everyone Else's 

I tell people all the time: the right time to buy depends on your numbers and your life stage, not your friend group's group chat. Buying tends to make the most sense when you plan to stay put for several years. If your finances are tight or a move might be coming, renting longer isn't failure. It's wisdom. 

A Faith Perspective on the Pressure to Buy 

I know what it feels like to think you're falling behind because you're not a homeowner. But your worth isn't tied to a deed with your name on it. Proverbs 24:27 puts it plainly: "Do your outdoor work and get your fields ready; after that, build your house." Preparation comes before the build — that's the order Scripture points to, and I believe it still applies. 

I don't believe faith promises a house will make you feel secure, or that the timing will ever feel perfectly obvious. What I do believe it promises is that wisdom counts the cost before it builds. 

Before you shop for a single home, I want you to calculate your honest housing target: 

1. Look at your actual take-home pay (after taxes) for one month. 

2. Multiply it by 0.25. 

3. That's your ceiling — the number to compare against any home you're considering. 

You don't have to decide to buy or keep renting today. You just need your real number on paper before that decision comes. 

The Bottom Line 

Renting isn't wasted money, and buying isn't automatic wisdom — the numbers tell the truth either way. If you take one thing from this episode, let it be this: prepare well, count the cost, and build when the foundation is actually ready.
