Building a relationship with a local lender can be beneficial for a number of reasons:

Better understanding of local regulations: Local lenders may have a better understanding of the local regulations and requirements that can impact your mortgage application. They can guide you through the process and help you avoid potential issues.
Access to local resources: A local lender may have access to resources that can help make the home buying process smoother. For example, they may have connections to local real estate agents, appraisers, and title companies.
Building a long-term relationship: By building a relationship with a local lender, you are establishing a long-term partnership that can extend beyond the initial mortgage transaction. This can be beneficial if you plan to refinance in the future or if you need additional financing for other real estate investments.
Community involvement: Local lenders are often invested in their local communities and may be more likely to offer specialized programs or resources to support local homebuyers. This can include down payment assistance programs, homebuyer education classes, and more.

In summary, building a relationship with a local lender can provide personalized service, better understanding of local regulations, access to local resources, the opportunity to build a long-term partnership, and community involvement. It's important to evaluate all factors when selecting a lender to ensure that you find the right fit for your specific financial needs and goals.
