We get an occasional complaint about other tenant's water usage but we basically indicate the water bill allocation was advertised when they committed to the lease and has not changed. 

Do not use % allocation for CapEx because CapEx does not change with value of property (it will change based on size of property however so need to consider that aspect)Maintenance - I typically bake this into CapEx costs which puts the total closer to around $225 for a 1,500 sqf SFR (also dependent on quality of property, upfront rehabbing, etc.).

@Alex HowardYou may be required to complete a partnership return to properly allocate the split among the profits of the flip."

Finally, if I had $100 a month to spend on marketing, where would you allocate that money towards marketing?

Though if you look at their urban planning reports they have allocated a fairly large part to building new SFH in the next 5-10 years.

In a pooled investment, the collateral is not bifurcated to each individual investor, it is allocated to the fund itself or the investment vehicle.

The cash I do have I wanted to allocate to marketing and do what I do best and sell.

The target return and capital allocation will also influence the choice.  

Your Chart of account will look like below:Savings AccountCapex ReserveR&M ReserveVacancy ReserveFor simplicity, say you have $100 as your basis of allocation, then you will transfer the actual fund from your checking to your savings reserve a total of $20 ($10 Capex, $5 R&M, $5 Vacancy) then record it QB as follows:Account                                      Debit             CreditSavings:Capex Reserve            $10Savings:R&M Reserve               $5Savings:Vacancy Reserve         $5Checking Account                                             $20And say you transferred $10 fund from savings to checking to cover actual expenses Capex $5, R&M $2 & Vacancy $3, then you will book it as follows:Account                                             Debit            CreditChecking Account                           $10Savings:Capex Reserve                                        $5Savings:R&M Reserve                                           $2Savings:Vacancy Reserve                                     $3Your savings/reserve account will then has a balance of $10 broken down as follows:Savings Account                  $10Capex Reserve                 $5R&M Reserve                   $3Vacancy Reserve             $2I also suggest that you this when you have enough funds to cover your reserves.

This has proven to be a very challenging and cumbersome process. the more I get in to this business the more I hear that pre-foreclosures and distressed owners may be a better allocation of my time and efforts.
