Should I buy another 3 decker in Worcester MA now or wait

[Quan Tran]

Good afternoon all, 

I just want your input because we want to buy another 3 decker to add to our portfolio but as you all know the price is very steep now.  If we are able to work out our number such as increasing our down payment in such a way that we get minimal positive cash flow and obviously just wait for a few years for appreciation to work its magic, would that be a good reason to buy now? Or should we wait?  Thank you so much for your input.
