Why applying to every bank at once matters
What can I afford on my salary?
South African banks work on two limits at once: your bond repayment should not exceed about 30% of your gross salary, and it has to fit inside what is actually left after your expenses. Luna Switch applies whichever is lower, which is what a bank does.
Your numbers
Monthly rands, before and after deductions.
Before tax and deductions. The 30% rule runs on this.
What actually lands in your account.
Living costs, car, credit cards, store accounts.
Leave at 0 if you have none.
A bank could lend you about
This is an estimate on the rules banks publish, not an offer. Your credit record, employment type and the property itself all change the answer.
Apply with this figure →Need the repayment, the transfer and bond costs, or what a deposit saves you? All four calculators are here. Calculated at prime, currently 10,50%, as published by the South African Reserve Bank. A longer term lowers the monthly repayment and raises the total interest you pay — switch the term above to see the difference.
How do I apply for a home loan through Luna Switch?
You make a free profile, answer three questions, upload the documents on your list, and choose which registered bond origination house submits your application to the banks. There are five steps and you can see exactly where you are at any point.
- 1
Work out what you can afford
Use the calculator above. Nothing is saved and you need no account to see the answer. You can ask for a standard bond, Shari’ah-compliant home finance, or both side by side.

Make a free profile
No password to invent or forget. A one-time code goes to your email address, and that is your sign-in.
- 3
Answer three questions
Whether you are salaried or self-employed, buying alone or with someone, first home or not. That builds your document list — only what applies to you.
- 4
Build your document file
Upload at your own pace, from your phone or laptop. Change an answer and the list rebuilds, and nothing you have already sent is removed.
- 5
Choose who submits it
Pick a bond origination house from the list. Your file crosses to them complete, documents and all, and they take it to the banks.
Who takes my application to the banks?
You choose, from a list of registered bond origination houses. The list is in alphabetical order with no rankings, no sponsored positions and no "recommended" badge. Luna Switch is not paid more by any one of them.
Unranked, always
Ordered by name and nothing else. No house can pay to appear higher, because none of them pays to appear at all.
They opted in
A house appears only because it chose to take applications from the public. Being a Luna Switch customer is not enough.
Your file goes whole
Not a lead with your phone number on it. The documents you uploaded cross with it, so you are not asked for them twice.
What documents do I need for a home loan in South Africa?
Most applicants need their ID, three months of payslips, three to six months of bank statements, and proof of address. Self-employed applicants need financials and tax returns instead of payslips. Luna Switch builds your exact list from three questions, so you never chase a document that does not apply to you.
| If you are | What the banks ask for |
|---|---|
| Salaried | South African ID, latest three payslips, three to six months of bank statements, proof of residence |
| Self-employed | ID, two years of signed financial statements, six months of business and personal bank statements, a SARS tax clearance, proof of residence |
| Buying with someone | The full set above for each applicant, plus your marriage certificate or ANC contract where it applies |
| A first-time buyer | The same as above. First-time buyers pay no transfer duty under R1,1 million, which the application works out for you |
Your list is built from your own answers and rebuilds if you change one. Nothing you have already uploaded is ever removed from it.
Why not just apply at my own bank?
You can, and many people do. The difference is how many banks see your application and how many times you have to assemble the same paperwork.
| Applying at one bank yourself | Through Luna Switch | |
|---|---|---|
| Banks that see it | One, the one you walked into | All of them together, through the house you choose |
| Roughly how many are approved | About half | About 84 in every 100 |
| Your paperwork | Assembled again for each bank you try | Uploaded once, kept in your own file |
| Knowing where you stand | You phone and ask | Five steps you can see, updated as it moves |
| What it costs you | Free | Free — the bank pays the originator on registration, never you |
Is my personal information safe?
Your documents are yours, they are never shared without your consent, and they are deleted on a schedule you can see. Luna Switch asks for POPIA consent in its own name before anything moves, and tells you the exact date your file would be removed.
Consent before anything moves
Nothing is sent to a bond origination house until you choose one and agree to it going.
No password to leak
A one-time code goes to the address on your record, so a typo sends it to nobody but the owner of that inbox.
A deletion date, not a policy
Your account page names the day your documents go. You are warned 14 days before, and again 3 days before.
Every access on record
Who opened your file and when is written to a log that cannot be edited afterwards.
Start your home loan application.
Free, no account needed to see what you can afford, and you choose who takes it to the banks.
