A holiday spending plan: one number per category. $1,600 plan, $1,030 spent by week 2 across three accounts, $400 card payment that is not spending.
Holiday Budget: One Number per Category, Checked Every Week
Most holiday budgets fail quietly. There's a total in someone's head, the spending lands on a credit card, a debit card and maybe a savings account, and nobody adds it all up until the January statements arrive. A holiday budget works better as a sm...

Are Security Deposits Income? 4 Ledger Traps That Inflate Rental Profit
A new tenant moves in, and your bank balance jumps. It feels like a great month. So, are security deposits income? Usually not when you receive them. A refundable deposit is money you hold for the tenant, and it often arrives in the same week as oth...

How to Calculate ROI on Rental Property Piece by Piece
Learning how to calculate ROI on rental property usually starts with one number: cash-on-cash return. That number is useful. It answers a narrow question — how much pre-tax cash the deal put in your pocket this year, divided by the cash you put in. ...

Flip Holding Costs: What One Extra Month of Rehab Really Costs
Most flip budgets treat flip holding costs as a single lump — "add a few thousand for carry" — then move on to paint colors and kitchen cabinets. The lump hides the only number that moves every calendar day: the monthly bill while the house sits unf...

Portfolio Cap Rate: Why It Isn't the Average of Your Properties' Cap Rates
Own three rentals at 6%, 8% and 10% cap rates and the natural answer to "what's my portfolio cap rate?" is 8%. Add them up, divide by three, done. It's also wrong, and not by a rounding error. A portfolio cap rate is the whole portfolio's net operat...

What Is a Rent Increase Worth? Price the Raise Before You Send It
What is a rent increase worth? Most landlords answer with one number: "$100 more a month." That's the smallest of three answers. A raise changes your cash flow, it changes the property's net operating income, and it can change whether your best tena...

Should I Pay Off My Rental Property Mortgage Early? Price It First
Should I pay off my rental property mortgage early? Ask ten landlords and you'll get two camps: the ones who want every property free and clear, and the ones who say debt is the whole point. Both can be right. The trouble is that most people pi...

New Year Budget Reset: Build Your 2027 Budget From Real Numbers
Here's an illustrative month. Take-home pay is $4,800. If you add up everything that left your accounts, you get $5,000, so it looks like you overspent by $200. Sort the same month properly and real spending was $3,200, with $1,600 left. Same m...

Cash-Out Refinance: Check the Cash Flow After the Refi
Ask a lot of investors to describe BRRRR and you'll hear four steps and a finish line: buy, renovate, rent, refinance, done. The refinance feels like the reward. The appraisal comes in, the lender wires the money, and the cash you put into the deal ...

Should I Buy Another Rental Property? Five Checks on the Whole Portfolio
Should I buy another rental property? It's tempting to answer that by looking only at the listing: the price, the rent, maybe a cash-flow estimate for that one house. That's half the question. The other half is what the new property does to the rent...

Flip Profit After Selling Costs: The Spread Is Not the Profit
Flip profit after selling costs is the number that decides whether a flip was worth doing, and it's almost never the number people quote. The quick version is sale price minus purchase price minus rehab. That's the spread. It's useful for a first lo...

Year-End Rental Property Tax Prep: A December Checklist for Landlords
Year-end rental property tax prep is mostly a records job, not a math job. The forms come later. What decides whether February is calm or chaotic is whether, by the end of December, every property has a full year of income and expenses sorted into c...

Is Principal Paydown Part of ROI? Return, But Not Cash
Every mortgage payment on a rental does two jobs. Part of it pays interest. The rest is principal paydown: it lowers the loan balance and adds to your equity. That second part is real return. It just doesn't show up in your bank account, and mi...

Does the 1% Rule Still Work? A Rental Property Reality Check
The 1% rule for rental property says a home should rent each month for at least 1% of what it costs to buy: $200,000 to buy, $2,000 a month in rent. It's popular because it takes ten seconds. So does the 1% rule still work? As a screen, yes. As an a...

Rental Yield vs Cap Rate: The Gross Yield Trap Hiding in Rental Listings
A listing that says "9.6% yield" is telling you something true and something incomplete. When people compare rental yield vs cap rate, the difference sounds technical: one divides rent by the price, the other divides what's left of the ...

First-Pass Deal Analysis: When a Quick Check Is Enough and When a Rental Needs the Deep Look
Most rental listings don't deserve an evening of your attention. A few do. A good first-pass deal analysis is how you tell them apart in a couple of minutes, and a deep analysis is what you do with the few that survive. The two jobs answer diff...

Vacancy Rate and Maintenance Reserve: How Operating Buffers Thin a Rental Deal
A vacancy rate rental assumption and a maintenance reserve rental line are the two operating buffers most optimistic underwrites leave off the sheet — or treat as a wish instead of a number. The rent still looks solid. The mortgage is fixed. Cash fl...

HELOC Interest-Only and Rental Cash Flow: What Changes (and What Doesn't)
HELOC interest-only payments can make a rental's month look easy. You pay the interest that accrued on the drawn balance. Cash flow on the spreadsheet improves. The quieter fact is what interest-only does not change: the principal is still waiting, ...

Flip Holding Costs and Your Maximum Allowable Offer
Flip holding costs are easy to treat as a later problem — something you'll feel after closing, during rehab, while the house sits. The quieter mistake is leaving them out of the maximum allowable offer you write before you buy. Once the offer is acc...

Short-term rental vs long-term rental tends to get argued with one number: what the place would bring in each month. On that number the short-term version usually wins. The number that decides it is what each version keeps after every cost, and how ...

The debt service coverage ratio on a rental property, usually shortened to DSCR, is the number a lender uses to decide whether the rent can carry the loan. It's also one of the most misread numbers in rental investing, because the version the lender...

BRRRR example: a full cost count leaves $17,000 after refinance, compared with a $5,000 quick estimate
Asset AFC
Cash left in the deal after refinance is the BRRRR number that tells you how much of your own money is still tied up in a property once the new loan closes. The formula is short: everything you put in, minus everything the refinance gives back. The ...
