Connect the purchase, the years of use and the eventual sale

Build five- and ten-year Costa del Sol ownership cash scenarios with explicit purchase, setup, recurring, replacement, contingency and selling inputs.

A Costa del Sol purchase budget often stops when the keys change hands. A useful ownership plan continues through moving in, ordinary bills, loan payments, replacements and an eventual sale. This workbook connects those stages without pretending to know future prices or combining several calculator totals that contain the same expense. Build the scenario from the actual home, the proposed funding and the way you expect to use it.

The tool above shows separate five-year and ten-year scenarios. Both start with the same initial cash requirement; the ten-year result is not added to the five-year result. Use the budget preparation worksheet to collect inputs and their sources. Blank amounts remain unknown. Zero is an explicit assumption, not a substitute for a bill you have not yet requested.

Start with the cash you must provide

Use the purchase cost calculator to organise the price, transaction assumptions, initial borrowing and cash needed. Transfer the checked own-cash requirement to this workbook. Do not transfer the whole purchase price again if the cash figure already reflects the initial loan advance. The workbook then adds future loan payments as separate cash movements, including whatever principal those payments contain.

This method follows household cash paid. It does not determine the economic cost of borrowing or value the home. If your purchase involves unusual funding, staged advances or payments that do not fit the fields, obtain a complete funding schedule before using a simplified scenario. Keep the original calculator inputs and professional explanations with the transferred amount so that another household member can follow its basis.

Keep setup and initial work distinct

Move-in spending includes the setup needed for your intended use. Initial works cover the separately scoped project you expect to undertake at the beginning. Use the move-in workbook and renovation cost tool to prepare those amounts. Check whether a quotation includes taxes, installation, professional services, delivery or other items before transferring it.

Make one line for each expense in your working record and identify where it enters this tool. If flooring appears in the renovation total, do not add it again as furniture setup. If the sale already includes an item, record that inclusion rather than entering an estimated replacement automatically. Keep optional upgrades separate from the minimum work on which your intended occupation depends.

Transfer a consistent annual ownership assumption

The annual ownership planner helps assemble community charges, utilities, insurance, maintenance and other recurring assumptions. Transfer the total excluding debt payments. Enter the assumed monthly loan payment separately in this workbook. A combined annual figure containing a mortgage payment would otherwise duplicate the debt amount. Check the same issue where community charges already fund a service you might have budgeted privately.

The tool holds the annual and monthly inputs constant. It does not forecast inflation, tariffs, interest changes or future charges. Run another scenario when you want to examine different assumptions. Use the same ownership share throughout: mixing half the purchase cash with the entire household’s annual costs produces an inconsistent result. Record whether your scenario concerns the whole home or one person’s agreed contribution.

Separate ordinary maintenance from replacements

An annual maintenance allowance and a specified future replacement serve different purposes. Review the maintenance guide and ask which projects are already covered by your recurring allowance. Enter additional replacements only where they are outside that scope. Their amounts and timing are your assumptions; the tool does not diagnose a roof, estimate equipment life or decide when a building project will be required.

The replacement entries are cumulative through each horizon. A ten-year figure of €20,000 includes the first five years, rather than describing only years six to ten. The tool rejects a ten-year cumulative replacement amount below the five-year amount. This keeps the two scenarios internally consistent while allowing you to change the wider brief and run a new pair of scenarios if the underlying plan changes.

Make the contingency visible

Contingency is an additional scenario provision. It is not a known invoice, a recommended reserve percentage or evidence that the budget covers every risk. Record which uncertainty it addresses and whether it overlaps a contractor’s allowance or a maintenance figure. Enter separate cumulative provisions for five and ten years, keeping the ten-year entry at least as large as the five-year entry.

Use the projection checking guide to review optimistic assumptions and missing categories. A larger contingency does not repair an unscoped project or missing legal information. If a cost cannot yet be estimated responsibly, keep it identified as unresolved rather than using a round number to create the appearance of a completed budget. The calculation should support the questions, not hide them.

Prepare two separate selling-cost allowances

Use the seller proceeds planner and sale costs guide to prepare the relevant assumptions for an exit at each horizon. Transfer selling costs excluding loan repayment. This workbook does not subtract sale proceeds or repay an outstanding loan at the end. Its result is gross household cash paid before those closing cash movements.

The five-year sale and ten-year sale are alternatives. The tool does not assume you sell twice. Sale taxes, fees and other costs need a suitable basis for your circumstances and future assumptions. The worksheet cannot determine them from the purchase price alone. Keep any loan balance and assumed sale value separately if you want to examine the wider position using the buy, rent or wait tool.

Follow a fictional arithmetic example

The example button loads own purchase cash of €175,000, setup of €5,000 and initial work of €10,000: €190,000 initially. Annual non-debt costs of €5,000 plus twelve monthly loan payments of €800 give €14,600 a year. The five-year inputs add replacements of €10,000, contingency of €5,000 and selling costs of €15,000. Gross five-year cash paid is therefore €293,000.

The ten-year alternative uses cumulative replacements of €20,000, contingency of €10,000 and selling costs of €20,000, producing €386,000. These figures are invented arithmetic inputs, not local prices, tax calculations, recommended reserves or lending terms. Neither total is a loss, a valuation or the net cost of ownership. The home and remaining debt have deliberately not been converted into an assumed end value.

Keep each version reproducible

Save in this browser only if you want a local copy in the current browser profile. Download JSON creates a portable scenario that this same tool can load. It does not create a website account or synchronise your figures between devices. Do not add personal account details to the worksheet. Someone sharing the browser profile may be able to open the saved scenario.

Print the summary for a household or adviser discussion. Keep the source date, quotation period and unresolved assumptions beside the printed result. Changing an input clears the displayed result until you update it, reducing the chance of reading an old total against new values. Clearing removes current entries and this tool’s own saved copy; it does not remove unrelated site data or another tool’s records.

Use the total to improve the decision

Compare the plan with your intended use, available funding and practical alternatives, using the buying decision guide. The UK government’s Spain property guidance provides background on independent advice. This workbook does not make an affordability assessment or replace legal, tax or technical appointments. It provides a transparent cash schedule you can question and revise.

Prepared on 10 November 2026. No independent professional review is claimed. Future rental income, interest on retained savings, opportunity cost, inflation, sale proceeds and the remaining loan are outside this gross-cash workbook. State those omissions whenever sharing a result so that the receiver understands exactly what the number represents.
