Three years ago I refinanced the loan on my fourth rental property and cut the monthly payment by about 18,000 yen. Last year I looked at refinancing another one, ran the numbers for two weeks, and decided not to do it. Same landlord, same spreadsheet habits, completely different answer. That is the honest truth about refinancing: it is never a blanket yes or no, it is a math problem that changes property by property.
After managing 9 rental units myself for more than 15 years, I have refinanced loans on 4 of them. I have also walked away from at least 6 offers that looked tempting on paper but did not survive a closer look. Here is the actual process I use every time a bank or a mortgage broker sends me a refinance pitch.

Before I get excited about a lower rate, I calculate how many months it takes to recover the refinancing costs. In Japan that typically means an arrangement fee (around 2.2 percent of the loan balance at many regional banks), a guarantee fee, registration tax for the mortgage change, and judicial scrivener fees. On a loan balance of 28 million yen, those costs usually land somewhere between 550,000 and 700,000 yen.
If the new rate saves me 15,000 yen a month, that 650,000 yen in costs takes about 43 months, or roughly three and a half years, to pay back. I only move forward if the break-even point is under 4 years and I plan to hold the property at least twice that long. If I am on the fence about selling within 5 years, refinancing almost never makes sense no matter how attractive the headline rate looks.

A lot of landlords get excited when they see a rate advertised at 0.8 percent, without checking what they are currently paying. I only start seriously evaluating a refinance when the gap between my existing rate and the new offer is at least 0.5 percentage points. Below that, the monthly savings get eaten alive by fees before they ever show up in my pocket.
On one of my properties I was paying 1.6 percent on a variable loan. A bank offered 1.35 percent, a gap of just 0.25 points. I ran the break-even math anyway out of curiosity, and it came out past 7 years. I passed. Six months later a different lender offered 1.05 percent, a full 0.55 point gap, and that one paid for itself in under 3 years. Patience matters more than speed here.
How Much Equity and Cash Flow History I Need
Banks will not refinance a struggling property just because you ask nicely. Before I even call, I make sure the loan-to-value ratio is under 80 percent based on a recent appraisal, and that the unit has kept occupancy above 90 percent for at least the past 24 months. Lenders want to see two full years of stable rental income on the tax filings, not just a good current tenant.
I also pull my own credit report and check that I have not taken on new personal debt in the past 12 months. A car loan or a large credit line, even one I am not actively using, can shave points off what a bank is willing to offer, or push my debt service ratio past their internal limit, which for most lenders I have worked with sits around 35 percent of gross rental income.

Knowing the tax rules turns a good investment into a great one.
Early repayment penalties are the one cost that catches new landlords off guard the most. My original loan on one property had a penalty clause of 1 percent of the remaining balance if paid off in the first 10 years. On a balance of 22 million yen, that is 220,000 yen gone before I even sign the new paperwork. Always read that clause before you get attached to a new rate.
Property reappraisal is another cost people forget. Some lenders require a fresh valuation, which can run 80,000 to 150,000 yen depending on the property type and location. And if the new lender insists on switching your fire and earthquake insurance policy to their preferred provider, you might lose a multi-year discount you had already locked in. I once nearly lost a 3-year prepaid insurance discount worth about 40,000 yen because I did not ask about this upfront.
My Refinance Decision Checklist
Whenever a new offer lands in my inbox, I run through the same short list before I spend any real time on it. This has saved me from wasting hours on offers that were never going to pencil out.
- Is the rate gap at least 0.5 percentage points below my current rate?
- Does the break-even point fall under 4 years?
- Do I plan to hold this property for at least double the break-even period?
- Is my loan-to-value ratio under 80 percent?
- Has occupancy stayed above 90 percent for the last 2 years?
- Are there early repayment penalties on my current loan, and how much do they cost?
- Will I need a new appraisal, and does that fee eat into the projected savings?
If a deal fails even one of these, I usually stop right there rather than digging deeper. Time spent chasing a marginal refinance is time not spent finding the next property.
When I Decide to Wait Instead
Sometimes the smartest move is simply to do nothing for another year. Rates move, my properties season, and occupancy histories get longer. Two of my current loans are sitting at rates I locked in 5 and 8 years ago that are still better than anything on the market today, so refinancing those would be a step backward.
I also hold off if I am planning a renovation within the next 12 months, since major work can temporarily lower a property’s appraised income and make a lender nervous, even if the long-term value goes up. Timing a refinance around, rather than during, a renovation has saved me from a couple of awkward conversations with loan officers.
That is the approach I use across all 9 of my properties: run the break-even math first, respect the rate gap, and never let a shiny percentage number distract me from the actual costs sitting in the fine print.
