Does it drag my valuation down if the recent nearby sales were all-cash investor purchases?

All-cash investor purchases nearby do not automatically drag a valuation down, but they can skew a naive comparison if those buyers paid below market for a property needing heavy repair work an owner-occupant would not take on. An agent reviews each comp's condition and terms before including it, weighting arm's-length owner-occupant sales more heavily when they exist nearby. Screening comps this way keeps an investor-driven sale from understating what a move-in-ready home is actually worth.
