How do I account for security deposits and tenant improvements in property management books?
The biggest mistake in property management bookkeeping is recording security deposits as income when they come in. That money belongs to the tenant until the lease ends. It is a liability, not revenue.
When you receive a security deposit, debit your cash account and credit a liability account like “Tenant Security Deposits Held.” That deposit sits on the balance sheet for the duration of the lease. When the tenant moves out, you either return the full amount (debit the liability, credit cash) or retain part of it for damages. Only the retained portion becomes income at that point. If you record the full deposit as income when received, your profit is overstated and your balance sheet is wrong.
Tenant improvement allowances follow a completely different path. When a property owner funds improvements for a tenant’s space, the cost gets capitalized on the balance sheet as a leasehold improvement. You don’t expense it all at once. Instead, you amortize the cost over the shorter of the improvement’s useful life or the remaining lease term. If you spend $20,000 on buildout for a tenant with 4 years left on their lease and the improvements have a 10-year useful life, you amortize over 4 years. That means roughly $5,000 in depreciation expense per year rather than a $20,000 hit in month one.
Both of these items need to be tracked per tenant and per unit. Property owners expect reporting that shows exactly which deposits are outstanding, which TI allowances are being amortized, and where each property stands financially. Lumping everything together makes it impossible to give owners the detail they need and creates a mess when tenants move out. Property management companies that manage multiple buildings for different owners need this level of granularity or monthly owner statements become unreliable.
In QuickBooks, set up sub-accounts under your security deposit liability for each property or tenant. For leasehold improvements, use fixed asset sub-accounts tied to specific units. This structure makes it straightforward to pull reports showing outstanding deposits by property and remaining amortization schedules by tenant.
One more thing to watch in Arizona. Security deposit laws require you to return deposits within 14 business days of move-out. If your books don’t clearly track what’s held and for whom, you risk missing that deadline and potentially owing the tenant penalties. Good bookkeeping protects the property owner legally, not just financially.
If your property management books have deposits mixed into income or TI allowances expensed in full when paid, the financials you’re handing to owners are misleading. Our Phoenix bookkeepers can help clean that up and build a tracking system that gives you accurate per-property reporting going forward.

What financial reports should a medical practice owner review monthly?
Focus on a P&L by provider, A/R aging by payer, collections vs charges ratio, overhead percentage, and days in A/R. Monthly review catches revenue and cash flow problems before they get out of hand.
Read answerHow do I track 1031 exchange cost basis and carryover depreciation on the replacement property?
The replacement property's basis equals the relinquished property's adjusted basis plus any additional cash you paid. Depreciation splits into two layers: carryover from the old property on its remaining schedule and a new 27.5-year schedule on any additional basis.
Read answerCan a real estate agent deduct staging costs, professional photography, and marketing expenses?
Yes. Staging, professional photography, drone footage, virtual tours, print marketing, online advertising, and open house expenses are all deductible on Schedule C. Track costs per listing when possible and only deduct your portion if expenses are split with the seller.

Arizona taxes prime contractors on 65% of the total contract price under the prime contracting TPT classification. Subcontractors, spec builders, and owner-builders each follow different rules. Getting the classification wrong is one of the most common filing mistakes.

Read answerHow do I reconcile my construction project budget against actual costs at month end?
Pull a job cost report showing budget versus actual by cost code for every active project. Calculate line-item variances, add committed costs from open POs and subcontracts, and update your cost-to-complete estimates. This monthly process feeds your WIP schedule and shows which jobs are really making money.
