In your example, if housing was a right, then it would be nonexcludable by definition, as the government cannot impede on your rights. So making housing a right doesn't mean the government will use taxpayer money to purchase and supply housing for only those without housing. On the contrary, it would compel the government to provide housing for every individual in the country, as rights are not exclusive to citizens (save voting and public office in some instances).
