Final answer:
The relevant tax credit for the client's situation is the Earned Income Tax Credit (EITC), which provides tax credits to low-income working individuals and families.
Step-by-step explanation:
The subject of this question is related to taxes and personal finance. The client is interested in purchasing a single-family home, and the question is asking which tax credit would be applicable in her situation. Based on the information provided, the relevant tax credit would be the Earned Income Tax Credit (EITC).
The EITC is a government program that provides tax credits to low-income working individuals and families. It is designed to help reduce poverty and incentivize work. In the case of the client, who is a single parent with two children, the EITC can provide a significant credit based on her income level.
Since the client has an income level within the eligibility range for the EITC, she may benefit from the tax credit. However, it is important to consult a tax professional or utilize tax software to calculate the specific amount she may be eligible for. The EITC can help increase her overall income and potentially provide additional funds that can contribute towards the purchase of a single-family home.
