@Tebes;
I'd like to differ slightly with @Litro. I think you can ESTIMATE the MARKET value of a house from its rent. But the relationship varies from town to town.
In Nairobi,the market value of a house comes to approximately 150 times the monthly rent. Thus if the rent is 20k,the market value is about 3m. In my estate,2br house are fetching between 30k to 35k in rent and anyone wishing to sell will not discuss anything with you if don't have 5m
As for the example given by @Litro; chances are that if the house currently fetching 50k rent is sold to a new owner at 10m,the new owner would soon raise that rent to 65k.......65 x 150 = 9.75m. BTW: if I bought it,I would do exactly that!
Perhaps this explains why rents have been shooting up so often....people are buying house for speculative reasons; when the sell them,the new owners are hiking up the rent to get decent returns on investment....
It's not a rule-of-thumb,but it's a good guide...estimate

Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
