Track Your Real Estate Portfolio Like a Stock Portfolio

Your brokerage app prices every position live. Your rental portfolio lives in a spreadsheet from three months ago. We built Portfolio to close that gap: every property you own, valued automatically as the market moves, with alerts for what needs attention.

Track Your Real Estate Portfolio Like a Stock Portfolio

Open your phone and your stock portfolio is priced to the second. Every position, current value, today's change, total return.

Now try to answer the same questions about your real estate. What is your portfolio worth this week? How much equity do you actually have? Which property is quietly losing money?

For most investors the honest answer lives in a spreadsheet that was accurate three months ago, plus a guess. Property is most people's largest asset class and the only one they still track by hand.

We built Portfolio to close that gap.

What tracking property like stocks actually means

A brokerage account does four things well. It prices every position continuously, it shows your cost basis and your gain, it totals the whole account, and it never asks you to update anything.

Portfolio does the same four things for real estate:

  • Live values. Every property you add is valued by the Resideline AVM, the same engine behind our reports, built on millions of closed sales. Values refresh automatically as new sales close around your properties. You never type a value into a cell again.
  • Real cost basis. Purchase price, loan balance, and every transaction you log roll into equity and return math, so appreciation is measured against what you actually paid, not a guess.
  • One number at the top. Portfolio value, total equity, appreciation since purchase, and monthly cash flow, all on one screen, all current.
  • Zero maintenance. The whole point. You open it, it is already right.

The part a spreadsheet will never do: alerts

A spreadsheet is passive. It waits for you to notice problems. Portfolio watches your properties the way a trading platform watches positions, and raises a flag when something needs attention:

  • Valued below purchase price. A property whose current value has slipped under what you paid.
  • Negative cash flow. Rent minus expenses minus debt service has gone red.
  • Renting below market. Your collected rent versus the market estimate for that address, flagged when the gap is real money.
  • Refinance and HELOC headroom. When your loan-to-value drops far enough that trapped equity becomes usable capital, Portfolio tells you roughly how much.
These are the checks a good asset manager runs weekly. Now they run themselves.

From deal to holding in one click

Portfolio pairs with Pipeline, our board for deals you are still chasing. Analyze a property with the Deal Analyzer or a CMA report, move it through the pipeline from first look to close, and when the deal completes, one click converts it into a tracked property in your Portfolio, with the analysis history attached.

Your acquisition numbers and your ownership numbers finally live in the same system. The valuation engine behind those numbers is the same one behind our public research, like asking rent vs actual rent and real home appreciation by city, both built from the closed-transaction data Portfolio prices against.

What powers the values

Every number in Portfolio comes from the Resideline AVM. It separates as-is value from after-repair value using real renovated sales you can inspect, it reads listing photos to grade property condition, and when a property recently sold it anchors to the actual sale instead of modeling around it. If you want to understand the engine in depth, we wrote about how our valuation model works and why condition is the blind spot in automated valuations.

The same honesty rules apply in Portfolio as in our reports. When a value carries real uncertainty, we show a range and say so. A portfolio tracker that flatters you is worse than a spreadsheet.

Who this is for

  • Landlords with two to twenty doors who want the weekly picture without the weekly bookkeeping.
  • Flippers holding a small inventory of projects, where each month of drift changes the exit math.
  • Out-of-state investors who cannot drive past their properties and need the numbers to do the watching.
  • Anyone who has ever updated a net worth spreadsheet by hand , promised to do it monthly, and stopped after February.

Frequently Asked Questions

How does Resideline value the properties in my portfolio?

Every property is valued by the Resideline AVM, the valuation engine behind our reports. It is built on millions of closed sales, separates as-is value from after-repair value using real renovated comparables, and refreshes automatically as new sales close near your properties.

Do I have to update values or enter comps myself?

No. Values refresh on their own. You add the property once, optionally log purchases, loans and rent, and Portfolio keeps the valuation side current automatically.

What alerts does Portfolio send?

Portfolio flags properties valued below purchase price, negative cash flow after debt service, rent meaningfully below the market estimate, and refinance or HELOC headroom when your loan-to-value allows usable equity.

Is Portfolio included in the free plan?

Yes. Portfolio and Pipeline are available to every Resideline member, including free accounts, alongside CMA reports and the Deal Analyzer.
