For what it's worth:-
In my experience by far the cheapest way to borrow money is to secure the loan on your house..... to most, this is a mortgage.
For some inexplicable reason, the greedy *ankers will use any excuse to hike their rates to usurious levels.
They lie--- the quoted interest bears no relationship to what you actually pay.....popular trick is to add the interest on the WHOLE amount,over the WHOLE term...."admin" charges, "setup" fees.....
last property i bought was a shop with living accom. over, which had a separate access. no mortgage, not even on the domestic part, but yessir, you can have a business loan at twice the mortgage rate.
Borrow against your house (remortgage often gets a better interest -rate, especially at the moment) but be prudent....IMHO you court disaster if your total borrowings have repayments exceeding 25% of your total income.
make sure you have a cash "cushion" in place, should you suffer illness/accident/redundancy.
providing you've done the long-term planning and risk-assessment and factored-in the future rise in interest-rates, it's safer to borrow this way, simply because a lot less of your income goes to interest and therefore equity builds quicker.
Many car -buyers have found that a 5-year loan doubles the cost of the car and by the time it's paid for, it's cream-crackered and barely makes a deposit for it's replacement.
Also give due consideration to the old saw...."if it flies, floats or f**ks, rent it!....sounds like hard won advice.
