Some sellers just pass on these hot potatoes, having milked the property by keeping all the rents and not plowing much back into it...Then the exit strategy is to sell to someone who may not recognize all the deferred capital expenses.Some ideas for avoiding the hot potatoes (where everything is at or near the end of its useful like) might be looking at age (but it sounds like most listings are a bit older), so you might only look at those properties with updated major systems and components (HVAC, plumbing, roof, windows, insulation etc).
