It is an "equitable right" of EITHER party when damages will not be good enough (inadequate) or the item is unique.

If you update most of the items during the rehab, you should have at least a few years with no/minimal repairs or capex expenses. 

@Ryan LinskeyThis specific item is not common, but service providers can charge itemized fees for pretty much anything if they wish.

The first is a two family complete gut and replace and the second is a single family home the requires a less extensive rehab but still some major items.

Action items are easy.It is the planning and setting things up is 80% of the time.

Some items such as your risk exposure, comfort with risk, wealth may play a role if you get an LLC or not.

If you did an inspection on it, some of those should have come out but you should look at the bigger items (roof, furnace, flooring, bathroom, kitchen) and see if those are in fair condition, at least to get you started.

My partner and I are planning to very thoroughly review all items in need of repair.

other items then in the closets in the rooms...
