Estimating Cash Flow On Lexington Single-Family Rentals

Wondering if a rental in Lexington will truly pay for itself each month? You’re not alone. With demand shaped by commutes into Columbia, nearby colleges, and regional employers, single-family rentals in Lexington can be solid long-term holds. The key is using local numbers and a simple process to estimate cash flow with confidence. In this guide, you’ll learn exactly which inputs to gather, the formulas to use, and how small changes affect your results. Let’s dive in.

Why cash flow matters in Lexington

Cash flow tells you whether a property supports itself after all expenses and debt payments. In Lexington, supply and demand are influenced by new construction, for-sale inventory, and investor activity, so your margin can tighten or widen quickly. Accurate cash flow estimates help you compare properties, negotiate better, and decide when to walk away. When you use Lexington-specific inputs, you get a clearer picture of both risk and upside.

What numbers you need locally

Gather these items for each property you’re evaluating in Lexington. Replace rules of thumb with actual quotes whenever possible.

• Market rent from 3–6 nearby single-family comps with similar beds, condition, and features
• Vacancy and credit loss expectation, often 5–8% for suburban SFRs
• Property taxes from the Lexington County Assessor or Treasurer for the exact parcel
• Insurance quotes for landlord coverage, including flood if required
• Maintenance and repairs budget, typically 5–10% of gross rent or about 1% of price per year
• Property management fee schedule, often 8–12% of collected rent
• Utilities you pay as owner, if any (water, trash, or other)
• HOA dues and any rental restrictions in the CCRs
• Capital expenditure reserves for big-ticket items like roof or HVAC
• Financing terms: down payment, rate, points, PMI if any, and closing costs

The cash flow formulas to use

Use these straightforward formulas. They help you compare apples to apples across properties.

• Gross Scheduled Income (GSI) = Monthly rent × 12 + other recurring income
• Effective Gross Income (EGI) = GSI − vacancy and credit loss
• Operating Expenses (OpEx) = Taxes + insurance + maintenance + management + owner-paid utilities + HOA + reserves + other admin costs
• Net Operating Income (NOI) = EGI − OpEx
• Annual Debt Service = Monthly mortgage payment × 12
• Cash Flow Before Tax (CFBT) = NOI − Annual Debt Service
• Cap Rate = NOI ÷ Purchase Price
• Cash-on-Cash Return (CoC) = CFBT ÷ Total Cash Invested

Keep two versions of your model: one for a base case and one for a conservative case. This helps you stress-test your assumptions.

Lexington costs to double-check

Local inputs can move your outcome more than you expect. Verify these before you finalize an offer.

• Property taxes: Confirm millage, assessed value method, and whether investor rates differ from owner-occupied rates.
• Insurance: Ask for landlord policy quotes that account for wind and flood exposure. Flood zones can require separate coverage.
• HOA and rental rules: Some communities limit leases or require minimum lease terms. Read the CCRs.
• Utilities and services: Confirm who pays water, trash, and any municipal fees.
• Vacancy and turnover: Check seasonality. Moves tied to school calendars, military transfers, or job changes can affect leasing timelines.
• Legal processes: Understand South Carolina eviction timelines and associated costs when estimating vacancy reserves.

Step-by-step example (hypothetical)

The following numbers are purely illustrative to show how the math works. Replace every figure with Lexington-specific quotes and actual property data.

Scenario A: Conservative older home

• Purchase price: 250,000
• Monthly rent: 1,600
• GSI: 1,600 × 12 = 19,200
• Vacancy at 7%: 1,344
• EGI: 19,200 − 1,344 = 17,856

Annual operating expenses (illustrative):

• Property tax: 2,000

• Insurance: 1,200

• Maintenance and repairs at 6% of GSI: 1,152

• Property management at 10% of collected rent: 1,785.60

• Owner-paid utilities/other: 600

• HOA: 0

• Capex reserve: 1,000

• Total OpEx: 7,737.60

• NOI: 17,856 − 7,737.60 = 10,118.40

• Financing: 25% down (62,500), loan 187,500, 30-year fixed at 6.5%

• Estimated monthly mortgage: about 1,185

• Annual debt service: about 14,220

• CFBT: 10,118.40 − 14,220 = −4,101.60

• Cash-on-Cash: Negative

Takeaway: At this price and rent, the deal runs negative. You would need a lower price, higher rent, or different terms to make it work.

Scenario B: Tighter price, higher rent

• Purchase price: 200,000

• Monthly rent: 1,700

• GSI: 20,400

• Vacancy at 5%: EGI = 19,380

• OpEx: 6,000 (assumed lower taxes or better efficiency)

• NOI: 19,380 − 6,000 = 13,380

• Financing: 20% down (40,000), loan 160,000, 30-year at 6.5%

• Estimated monthly mortgage: about 1,011

• Annual debt service: about 12,132

• CFBT: 13,380 − 12,132 = 1,248

• Cash-on-Cash: 1,248 ÷ 40,000 = 3.12%

Takeaway: Modest adjustments in price and rent swing the deal to positive. This shows why updated comps and strong negotiations matter.

What moves the needle most

When you model multiple versions of the same property, test these variables first. They often make the biggest difference.

• Purchase price and seller concessions
• Rent level and any additional income (pet fees, parking, utility reimbursement)
• Property taxes and insurance quotes
• Property management fees and vacancy rate
• Maintenance and capex reserves, especially for older systems
• Interest rate, down payment, and points

A small change in any one of these can flip negative cash flow to positive. Always run sensitivity checks before you finalize your offer price.

After-tax considerations to model

Taxes affect your return but not your cash flow. You should model both before-tax and after-tax outcomes with a qualified tax professional.

• Depreciation: Residential rentals depreciate over 27.5 years, which can lower taxable income.
• Interest deduction: Mortgage interest can reduce taxable income.
• South Carolina state income tax: Factor state tax when reviewing your after-tax return.
• Exit planning: If you plan to sell, ask about capital gains planning and whether a 1031 exchange may fit your goals.

Local checklist to complete before you buy

Use this quick workflow to replace estimates with Lexington-specific data.

1. Rent comps and demand

• Pull 3–6 recent single-family rent comps in the same neighborhood or within about a mile.
• Confirm comparable features like beds, baths, lot size, garage, and amenities.
• Note commute times and neutral school zone information as context for tenant demand.

2. Taxes and insurance

• Retrieve the exact tax bill and confirm the assessment method for non-owner-occupied property.
• Get 2–3 landlord insurance quotes. Ask about wind, flood, liability limits, and deductibles.

3. Property condition and reserves

• Inspect major systems: roof, HVAC, plumbing, and electrical.
• Build a 5–10 year capex schedule and set your annual reserve accordingly.

4. Management, leasing, and legal

• Get fee schedules from 1–2 Lexington-area property managers, including leasing and renewal fees.
• Understand average days-to-lease, seasonal trends, and typical tenant turnover costs.
• Review South Carolina landlord-tenant procedures and local court timelines for evictions.

5. Financing terms

• Obtain investor-rate quotes from local lenders or brokers.
• Clarify down payment, points, closing costs, and any PMI requirements.

6. Risk checks

• Review FEMA flood maps and county GIS for floodplain status.
• Confirm HOA dues, rental restrictions, and any local licensing or registration requirements.

Putting it all together

When you combine verified Lexington rent comps, the exact tax bill, real insurance quotes, and realistic maintenance and management budgets, your cash flow picture becomes much clearer. Use the formulas above to calculate NOI, debt service, and cash flow, then run a conservative version to see your downside. If the deal only pencils with perfect assumptions, keep looking. The best investments survive a conservative model and still meet your return goals.
