Expenses such as roof, utilities that serve the entire building, and other building wide expenses are expensed on a pro-rata basis.

Effectively they owned the same pro rata interest as the parent LLCs, just with another legal layer.  

Pre-paid rent refunded on pro-rata if owner breaks the lease.- Owner agrees to allow sub-letting.  

Im a new REI in Las Vegas NV Im in the process of getting my LLC but I wanted advice on if I should be applying for a pro rata or non pro rata LLC.

The original pro rata split per limited partner s/b retained, i.e. their splits should be cut in half.    

In 07 cap ratAes where low, so in theory it was less risky right ?

All expenses are done on a pro-rata basis using square footage as the calculation.If you are buying future properties, some mortgage brokers will not consider future rental income on the subject property unless you can demonstrate experience as a landlord, so being able to show that you were partially renting your home would likely count (depending on the broker).  

So say tenant A consumed 60%, he will end up paying 60% of common area as well.Now, a new tenant came in on 1st of May but his meter wasn't installed until 11th May, we agreed that they will pay on pro rata basis.I am stuck calculating the bills now, and will need some major math work.Here is what i haveTotal Bill Amount 75,256 (don't worry, its not USD)Total units consumed 8752Bill Date 29th April to 29th MayVacant Unit in building - 106 Units consumedTenant A 1717 Units consumedTenant B 3541 Units consumedTenant C 2303 Units consumed for 19 days (11th May to 29th)Total 7667 UnitsCommon area 1085If i take 2303 Units and divide by 19 days, it gives me 121 Units a day and multiply that by 29, i will in total get more money from all tenants than combined bill, which is unfair.Please suggest a best way to calculate.

However, this may not necessarily fit your lifestyle and if you have held them for up to 30 years the pro-rata tax-free benefit perhaps won't be that helpful.I highly recommend going to @Johnson H. meetup in San Jose.

So it sounds like you would give each a pro-rata amount not the same for everyone.
