Let's assume you can get 25,000/month after paying land rates, KRA tax, etc. That's 300,000/- per year. The purchase cost will be 6mn after all the expenses. The return is 5%.
If you have to borrow (at current rates of 18-25%) a significant portion of the cost then the return plummets.
Greedy when others are fearful. Very fearful when others are greedy - to paraphrase Warren Buffett
