Let to Buy is one of the most mis-structured mortgage strategies in the UK.
The mistake? Treating two mortgages as separate applications instead of one coordinated plan.
Without proper strategy, applications fail for predictable reasons:
β οΈ Rental income failing ICR stress testing
β οΈ Overestimated rental projections
β οΈ Insufficient equity after valuation
β οΈ Residential affordability reduced by the Buy-to-Let commitment
β οΈ Dividend or bonus income assessed conservatively
β οΈ Lenders selected independently rather than as a compatible pair
If one lender declines, the onward purchase can be placed at risk.
