What? $200 year salary will have tax on it. Thats not your take home, then you also have to eat, live, pay rent for your current place.
And sure thats probably slightly easy calculated but personally for me, living 5 years very frugual and then buying a house and then doing another 5 years and then stop working, is very reasonable when you have a salary like that.
The first 5 Years might mean saving a lot, but then you own a house. Payed, mortgage free; Very low base costs.
Depending on how big that house is, you are now able to invest even more longterm: Solar Power for example to keep your utility costs very low.
