This is my personal experience:
In early 2002,an opportunity arose to buy a flat in a very decent neighbourhood. Cost was Sh2.5m. Terms were: deposit 10%,balance payable in 15years at 15%pa interest. Therefore,monthly installments were sh31k
At that time I was paying sh17k rent for an identical flat (in the same block!). I took the deal an moved to the 'my' flat.
Now instead of paying the agreed 31k for the mortgage,I paid 40k every month. At that rate,I had calculated that the loan would be finished in 8 years instead of the agreed 15.
Two and a half years later,I lost my job and I had to cut the payments back to 30k. But by that time,the loan balance had gone so below the standard amount that the minimum installment payable was 28k instead of 31k.
So,even with 30k,I was still paying more than the required amount.
Over the next four years,I slowly upped the installment to 35k as my finances improved. By November last year,the loan balance was 930k. Now if I had stuck to the agreed 31k installment,my balance at that moment would have been 1.77m....a whole 840k more.
Nov last year I did some digging and found some money sleeping in a dormant pension account...from my previous employment. I cash it out and cleared the 930k loan balance. Now I am debt-free...making me one of the richest people in the world!
By the way,the flats now are fetching up to 30k per month in rent and their market value is well over 5m.
Moral of the story:
Don't spend too much time complaining that mortgage rates in Kenya are too high. If you don't like them,move to country where the rates are cheaper....houses in Japan are at least ten time more expensive than in Kenya.
The mortgage installment for the house you are staying in is approximately double the rent you are paying.
Your rent will double in the next five years. Decide now whether you want to be paying the rent or the mortgage in 2014....the two amounts will be the same
When you sign up for a mortgage,make sure you can afford slightly more than what the bank asks for...and do pay the little extra
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
