Your last paragraph hit the nail on the head as far as what I was thinking; buy the biggest MF I can find so to spread risk across number of units.

It will eliminate me having to pay their bills though, which are roughly 4K/yr.I’m wanting to know how much separate utilities will add to resale value.

We just want to eliminate doubts for the sellers and appraisal is one of them. 

The current condition of the windows makes the best option to do a full tear out and replace with new construction windows with a nailing fin and J-channels for the subsequent new siding to fit in.This is a rental property, but I intend to keep it for 30 or more years, so I want to pay enough to get a good quality window that will hold up well over many years.I am curious is anyone has suggestions.

That alone eliminates 90% of the bad applies.

Others nailed it on the head.

@Rose Higgens You nailed it!!

It just depends on the quality of the rental and other factors.If a renter leaves a few nail holes in a wall, I usually leave them because the next renter is likely to put up pictures and can use the same holes.

You already have a track record in real estate, don't sell yourself short.Stewart hit the nail on the head with why you should go after new deals, rather than bring investors into deals you already have.

@Anthony Thompson you hit the nail on the head.
