If you have a 25 year roof with 10 years left and it will cost $15,000 to replace, you need to budget an additional $1,500 per year going forward to cover that specific item.  

Hence why just using an overall number can be more accurate than trying to itemize the individual items.Some specific items includeTaxesInsuranceUtilities (common areas, during vacancies)VacanciesProperty management AdvertisingLegal costs (leases, evictions)GroundskeepingMaintenanceMake ready in between tenantsMortgage payments aren't included.

They post a basic list but then there is a list thats put into Excel which makes it easier to search and find specific items of interest as its 800 plus pages of information.

If there is a specific item or type of expense I can give you better guidance. 

I'd like to address some of the specific items conveyed in this thread.With respect to the Birmingham situation from many years ago, all of our buyers were compensated for their losses (as the author of that thread confirmed towards the end of the thread).

Parks have a lot of specific items and by going with their contract on the buy side, it will be a tremendous advantage to you. 

After you come through title with no issues, closing the deal is standard business....BUT you may have some state-specific items you want to talk with an attorney about.

If the answer is no, then the likelihood is that the market may no be responding to that specific item. 

I am making a checklist of items to look at in each unit, covering all items for unit from flooring type, need to replace, overall condition of unit, specific items such as doors, windows, cabinets, etc. 

Here are some things to include.Copies of leases and applicationsAccess to Yardi, Onesite, or other PM softwareDocumentation of debts, past due etc.Rental licenses3 years taxesRent roll with lease start, end, amount, and deposit. be sure PA prorates rents and transfers deposits with interest)Service agreements lawn, snow, cleaning, laundry etc.Copies of tenant notices  given within 90 daysOperating statements 3 yearsDisclosures, LBP, etcContracts for improvements in last 3 yearsEmployment contracts/ payroll Insurance policies and claims history 5 yearsinventory of property on site (office furniture, common area items, etc)Repair records for the building 2 yearsCopies of bills such as heat, electric, water, etc to verify (also helps with transfer)Copies of current inspections.Boiler logs Past litigationCertificate of occupancy Tax records (we will pull)warranties sill in effectfloor plansestoppel agreementZoning Historic designationPrepare lease assignmentsPrepare prorated rent and deposit agreement for closingThere are often many more property specific items.
