Multi-Currency Setup for Cross-Border Portfolios

Platform Tutorials · 5 min read

1st Numbers is built for international property investors. Whether you have properties in London, Lagos, Dubai, and New York — or plan to expand across borders — the platform handles multi-currency portfolios natively.

Supported Currencies

1st Numbers supports 10+ currencies with automatic FX normalization:

  • 🇬🇧 GBP — British Pound
  • 🇺🇸 USD — US Dollar
  • 🇪🇺 EUR — Euro
  • 🇦🇪 AED — UAE Dirham
  • 🇳🇬 NGN — Nigerian Naira
  • 🇿🇦 ZAR — South African Rand
  • 🇨🇦 CAD — Canadian Dollar
  • 🇦🇺 AUD — Australian Dollar
  • 🇨🇭 CHF — Swiss Franc
  • 🇸🇬 SGD — Singapore Dollar

How Multi-Currency Works

1. Set Currency Per Property

When you add a property, you select its base currency. This is the currency in which the property was purchased and generates rent.

Example Portfolio: Property 1: London flat — GBP £350,000 Property 2: Lagos house — NGN ₦120,000,000 Property 3: Dubai apartment — AED 1,800,000 Property 4: New York condo — USD $500,000

2. Automatic FX Normalization

Behind the scenes, 1st Numbers converts all property values, rents, and costs to your reporting currency (default: GBP) using current FX rates.

This gives you one consolidated view of total portfolio value, equity, and yield — regardless of how many currencies you operate in.

Normalized Portfolio View (GBP): London: £350,000 Lagos: ₦120m → £60,000 (@ 0.0005 NGN/GBP) Dubai: AED 1.8m → £396,000 (@ 0.22 AED/GBP) New York: $500k → £395,000 (@ 0.79 USD/GBP) Total Portfolio Value: £1,201,000

3. View Currency-Specific Performance

Go to Currencies in the sidebar to see:

  • Portfolio exposure by currency (% breakdown)
  • Properties per currency
  • Total value and rent in each currency
  • Current FX rates vs your base currency
  • FX impact on total portfolio value

This helps you understand currency risk — if 60% of your portfolio is in NGN and the naira weakens 10% against GBP, your GBP-denominated portfolio value drops accordingly.

Setting Up Multi-Currency Tracking

Step 1: Choose Your Base Reporting Currency

Your base currency is the currency used for consolidated reporting. Most users choose:

  • GBP if UK-based or reporting to UK investors
  • USD if US-based or using USD as a global standard
  • NGN if primarily Nigerian-focused with some international holdings

You can change this anytime in Settings.

Step 2: Add Properties with Local Currency

When adding a property:

  • Enter purchase price in the local currency (e.g., AED for Dubai)
  • Enter rent in the same currency
  • Select the correct currency from the dropdown

Don't convert manually — the system handles all FX automatically.

Step 3: Add Mortgages in Property Currency

If you have a mortgage on a Dubai property, enter the loan amount and payments in AED. The system normalizes debt exposure to your base currency for LTV and DSCR calculations.

Step 4: Track Income & Costs in Local Currency

Record rent receipts, maintenance costs, and agent fees in the property's currency. Everything auto-converts for portfolio-wide reporting.

FX Rates and Updates

1st Numbers uses indicative FX rates updated periodically. These rates are for portfolio tracking and performance analysis — not for live trading or precise accounting.

For tax filings or official reporting, consult your accountant and use HMRC/official exchange rates.

FX Risk: Currency fluctuations impact portfolio value. A 10% naira depreciation reduces the GBP value of Nigerian properties by 10%, even if local NGN values are stable. Diversification across currencies can hedge this risk.

Example Use Case: UK-Nigeria-UAE Portfolio

Portfolio Structure: Entity 1 (Personal) — Base: GBP → 2 London flats Entity 2 (Obi Properties NG Ltd) — Base: NGN → 5 Lagos houses Entity 3 (Dubai SPV) — Base: AED → 1 Dubai apartment Dashboard View (Base: GBP): Total Value: £2.4m - London: £900k (37.5%) - Lagos: £800k (33.3%) - Dubai: £700k (29.2%) Monthly Rent: £18,500 - London: £6,000 - Lagos: £8,000 (₦16m) - Dubai: £4,500 (AED 20,500) Weighted Yield: 9.25% (gross) FX Exposure: 62.5% non-GBP

Common Questions

Can I change the base currency later?

Yes. Go to Settings → Preferences and select a new base currency. All reporting updates instantly.

What if FX rates change significantly?

Your portfolio value (in base currency terms) will fluctuate. This is real — if you hold NGN properties and naira weakens, your GBP wealth decreases even if local property values are stable.

Do I need to manually update FX rates?

No. Rates update automatically. You can view current rates in the Currencies section.

Can I add custom currencies?

Not yet. If you need a currency not on the list, contact support.

Next Steps

Once your multi-currency portfolio is set up:

  • Monitor currency exposure in the Currencies page
  • Model FX scenarios in forecasting (coming soon)
  • Use capital strategy tools to compare acquisitions across markets in normalized terms

Cross-border investing is complex. 1st Numbers makes it trackable.
