Lead Qualification: Pre-Approval, Affordability, and Persuasion

Pre-approval is a rigorous assessment of a buyer’s financial capacity utilizing credit scoring and risk analysis. Lenders employ statistical models like FICO to evaluate creditworthiness, assigning a numerical score based on payment history, amounts owed, length of credit history, credit mix, and new credit.
* Equation 1: FICO Score Function (Simplified Representation)
* F = w₁P + w₂A + w₃L + w₄M + w₅N
* Where:
* F = FICO score
* P = Payment history score
* A = Amounts owed score
* L = Length of credit history score
* M = Credit mix score
* N = New credit score
* wᵢ = Weights assigned to each factor (determined by FICO algorithms).

Risk is assessed using metrics like Loan-to-Value (LTV) ratio and Debt-to-Income (DTI) ratio.
* Equation 2: Loan-to-Value (LTV) Ratio
* LTV = (Loan Amount / Appraised Property Value) * 100
* Equation 3: Debt-to-Income (DTI) Ratio
* DTI = (Total Monthly Debt Payments / Gross Monthly Income) * 100

Borrowers with lower DTI ratios are less likely to default on their mortgage payments (Gerardi et al., 2010).

Agents can formulate hypotheses about the relationship between pre-approval amounts and actual purchase price❓s. Correlation analysis (e.g., Pearson’s correlation coefficient) can be used to test these hypotheses.
* Equation 4: Pearson’s Correlation Coefficient (r)
* r = (Σ((xᵢ - x̄)(yᵢ - ȳ))) / (√Σ(xᵢ - x̄)² * √Σ(yᵢ - ȳ)²)
* Where:
* xᵢ = Pre-approved loan amount for individual i
* x̄ = Average pre-approved loan amount
* yᵢ = Final purchase price for individual i
* ȳ = Average final purchase price

Behavioral economics highlights the influence of psychological factors on spending decisions. Prospect Theory suggests that individuals make decisions based on perceived❓ gains and losses relative to a reference point (Kahneman & Tversky, 1979). Framing Effects influence buyer perceptions.

Agents can construct simple economic models to understand buyers’ affordability constraints.
* Equation 5: disposable income❓ Calculation
* DI = GI - T - FE
* Where:
* DI = Disposable Income
* GI = Gross Income
* T = Taxes
* FE = Fixed Expenses (e.g., car payments, student loans)

Estimating the marginal propensity to consume (MPC) for housing is crucial.
* Equation 6: Allowable Monthly Housing Costs
* AHC = MPC * DI
* Where:
* AHC = Allowable Monthly Housing Costs

Home buying decisions are often influenced by social networks (Granovetter, 1973).
* Nodes: Individuals in the network.
* Edges: Relationships between individuals.
* Centrality Measures: Metrics like degree centrality and betweenness centrality.

Social influence can be measured using a Likert scale to determine how much influence someone has on their decision. Source credibility and argument quality are key determinants of persuasive influence (Petty & Cacioppo, 1986).

The Real Estate Settlement Procedures Act (RESPA) regulates affiliated business arrangements between real estate agents and mortgage providers. Agents must disclose any affiliated business relationships in writing at the time of the recommendation.
