For owner self occupied purchase, PITI w/20% down equal rent is a good starting point, since the tax benefit will well compensate the 20% down payment. If you find a good one you like, you might want to jump off the fence as it’s not far away from the bottom.

Before investors flood in, another 10%~15% price drop will be expected…
