TTs pays for pro rata share of taxes, insurance, and CAMs (including short term roof, HVAC and parking repairs).  

Partners B-D take their money and run.Prop 1 LLC is now getting it's 1065 and associated forms ready for 2022 taxes (totally theoretical :) ).When filling out Form 8824, Part III, does Prop 1 LLC use the entire property value, or just Partner A's pro rata share?

So, if you’re in MN and making good income that can put you around 50%.Per the IRS website:Nonqualified distributionsA distribution that is not a qualified distribution will be partially included in gross income if there are earnings in the account.The distribution will be treated as coming pro-rata from earnings and contributions (basis).The 10% tax on early withdrawals may apply to the part of the distribution that is includible in gross income.https://www.irs.gov/retirement-plans/designated-roth-accounts-distributions Other than that I agree completely.

@Jesse EastA lot of gurus preach writing off "vacations" for taxes and it often gives the wrong impression.If there is bona fide business on a mixed trip that includes vacation, the trip generally would be deductible in part (i.e. pro-rata).The IRS would take issue with a taxpayer meeting with an agent on the fly and viewing a few properties with no actual intention to follow through and invest in that area and then writing off part of the trip. 

Then you would bill back the tenants pro-rata.

I get them for cities when I am building a subdivision.they can be pretty hard for most builders to get unless they are very successful and have good financials which can be a challengehow we handle these is we hire the GC for a flat fee 10 to 15k per house... pay them at draw time a pro rata share with the major share due at CO .... 

My wife and I find the deals and manage the details, our family puts up the cash, we split 50 (us)/50 (balance to other members based on pro rata share).

(b)Escrow Required: With each installment Buyer shall deposit in escrow with Seller a pro rata part of the estimated annual ad valorem taxes and casualty insurance premiums for the Property.

Per the OP, the investors are pro-rata into the LLC according to their equity investment.

Tenants were billed their pro rata share (CAM, TAX, INS) but the tenants were responsible for repairs in their spaces with the exception of HVAC.I would say, if the tenants are already accustomed to NNN why change it?
