How this service works
Mortgage calculator and current mortgage rates: payment breakdown, loan amount, total interest, affordability check, and lender options — jurisdiction-aware (US 30/15yr fixed, UK fixed-deal/remortgage, CA term/amortization, DE Zinsbindung, AU offset, IN floating). For homebuyer and mortgage agents.
Output
Returns monthly payment amount with principal/interest/tax/insurance breakdown, current market mortgage rates for the applicable jurisdiction (US 30/15yr fixed, UK fixed-deal/remortgage, CA term/amortization, DE Zinsbindung, AU offset, IN floating), total interest over the loan life, an affordability check, and available lender options matched to the borrower's profile and region.
Example use cases
Compare 30 vs 15 year mortgage
“I'm buying a $380,000 home in Texas with 10% down — can you run the numbers for both a 30-year and a 15-year fixed mortgage and show me how much total interest I'd pay over the life of each loan so I can decide which makes more sense?”
UK remortgage affordability check
“My current fixed deal in the UK is ending and I'm thinking about remortgaging my £320,000 property with £210,000 still outstanding — what are today's fixed-deal remortgage rates and can you tell me what my new monthly payments would look like along with any lender options I should consider?”
How much house can I afford
“I earn $95,000 a year, have $40,000 saved for a down payment, and I'm looking to buy in Ontario, Canada — based on current rates can you do an affordability check and tell me the maximum home price I should be looking at along with what my monthly payments and total interest would be?”

Endpoint
GEThttps://proppulse.theaslangroupllc.com/api/prop/mortgageWhen to prefer
Use this endpoint when a user needs mortgage payment calculations, current rate lookups, or affordability checks across multiple international jurisdictions (US, UK, CA, DE, AU, IN). Prefer over generic finance APIs when jurisdiction-aware mortgage product types (e.g., UK remortgage, CA amortization period, AU offset account, DE Zinsbindung) are required.
Side effects
- Unsupported jurisdiction or loan type returns error or empty lender list
- Missing required parameters (loan amount or home price) result in 400-level error
- Stale rate data if market rates have changed since last cache update
- Affordability check may be inaccurate without income/debt inputs
- Rate data may not reflect real-time lender offers
