I proposed the question if the separation of funds was for asset protection.  

In Japan, it's the opposite, at least for structures (land and building values are separate). 

Two separate property appraisers (at the direction of the lender) were sent out to appraise, and neither was willing to appraise it as a "residence", and thus financing fell through (conventional primary loan).

One workaround could be keeping a separate spreadsheet to track your adjusted tax basis accurately and only using Stessa for operational insights.You could also reach out to a cpa and see if they have a specific recommendation for software to use.  

This lets both parties separate rather than dragging out the relationship.

The idea is to convert a multi-family building into condos; but not in the traditional sense where you separate pre-existing apartments into their own condos; but in a way where you combine the common areas of all of the apartments in that whole building, and turn the individual rooms within those apartments into condos themselves; thus transforming the hallways, kitchens, bathrooms, living rooms, dining rooms, porches, balconies into common areas of the condos. 

(I actually laughed when I first learned this.)10% property management fee (With separate charges for new leases, repair management, and rent collection—what exactly does this cover?)

definitely need to have lawyer look at it.Risks/additional hurdles- On the practical side, the absence of deeded rights makes tenancy in common ownership considerably more risky than condominium ownership, even where the TIC owners have separate financing.

I would pay them separately rather than giving a rent credit.

If you want to quote out high efficiency boilers for six Tripple deckers for example requiring installation of separate gas, meters etc. etc. - that might be a situation where you would want to work with a contractor directly because you would have lots of different options with widely varying costs.
