Most of them will ask for a new dimensional shingle roof.

However, you can only put one layer of shingles due to weight.Plumbing may be different on older units, called quest pipes, now illegal.

I look for the biggies like sagging roof, missing shingles or tiles, rotted siding, etc... if the place looks decent, then my tail is wagging.

Hi,I’m looking at a 4-unit multifamily in New England and the property has asphalt shingles siding.  

Roof: Asphalt Shingles common last 20-30 years here in GA.

For Sale: Surfside Beach home, Top quality construction, built strong to withstand tough weather, up to code,12"X12" pilings, fully furnished, high profile architecture roof shingles, wrap around covered porch for your 360 degree cool shade enjoyment, reduce direct sun lights, keeps new paint looks last longer and reduce chance of window leaks.

What I found (to my pleasant surprise) was that I could get higher quality major items (carpet, cabinets, appliances, shingles, lumber, doors, windows, etc) for either the same price or less from the specialty shops rather than the big box stores.

It also usually voids the warranty on the shingles.

I have asbestos shingles, vermiculite insulation and white asbestos hvac duct tape in my unit and I have to disclose it.
