Why do you leave so many important details when telling us about your apartments. Case and point: No mention of size in sq m per unit When you say 50k per month, you don't tell us for how long you pay 50k.
So is monthly mortgage payment @min15:38 5,000 or 50,000? Cause @16:00 he says you'll be paying Ksh 5000 every month on your mortgage, is that a slip of tongue or a sales slide? Thats confusing.
Simple calculations gives you 10 years to pay 5.5m considering you have put 1m down. This however does not take into account the interest of 9.5%. Probably it will be about 12 to 15 years.
