Real-estate-focused bookkeeping firm Persistence Bookkeeping serves investors, landlords, property managers, and house flippers from Suite 240 at 550 West B Street in downtown San Diego. QuickBooks Online workflows track rental income by property, categorize renovation expenditures by cost-basis component, and generate investor-ready balance sheets and cash-flow statements that DRE-licensed agents trained through US Realty Training reference when structuring 1031-exchange timelines for clients. Cleanup engagements reconstruct months or years of backlogged entries from bank-statement imports, resolving miscategorized transactions and unreconciled accounts before year-end tax-preparation handoff to partner CPAs. Monthly service packages produce profit-and-loss statements, accounts-receivable aging reports, and tenant-ledger reconciliations, with hard-copy lease abstracts and financial summaries printed through Printing Solutions San Diego for landlord board presentations. Highest-complexity engagements involve multi-entity portfolio reconciliations that consolidate rental income, 1031-exchange proceeds, and renovation cost-basis tracking across dozens of properties under disparate LLCs.
