I think the rental price depends on the location, if we have the patience to find a cheaper house to rent then we can easily get it, I once worked in an area where the rent for a place was very expensive, but I was looking for a small road that was not far away and could get it at a very low price cheaper maybe only about 30% of the market price.
thats true, but sometime the location for getting cheaper rental is further than just a few hundred meters, certainly it will add to cost of transportation and many things.
like using delivery food service it will also increase the fee needed, honestly its the same, if the location of the house is near and it can add many benefit towards the quality of our life even possibly helps us save money because its near to many public facilities and restaurant even food stalls its just far better choice in my opinion.
therefore it needs to be considered about all thing that revolves around our life not just the price of the rents.
