I just started a separate thread on this subject.

It was 6 properties covered by one mortgage and the borrower bought the package with 6 separate mortgages. 

The second problem here that I've encountered with lenders that are willing to underwrite multiple parcels as separate to loans - two of the buildings are studio/small 1br cabins with footprints of ~500sqft.

Multiple sub contractors with multiple separate contracts are not allowed.Repairs/Improvements must be completed by licensed contractor(s) as required by local/state municipalitiesRepairs cannot be completed by a related or interested party (i.e. relative, real estate agent, seller, broker, etc.)Borrower selects contractorContingency ReservesMinimum 10% is required.

I like the liability protection that comes from separating out the businesses.

For every property you own you should be opening up separate checking and savings accounts for the ease of book keeping and accounting, correct?

The estate is currently being sold by 4 separate siblings and i think it is priced high if it is just the house, but not sure how to value or what to offer because of the lot rent income. 

Separate electric meters(if multi)6.

So, it's sort of two separate topics here: 1.

Lots about permitting, fire separation, inspections, managing subs, all of it down to the landscaping.
