15 Mortgage FAQs: Your Massachusetts Mortgage Guide 

Thinking about buying a home or investing in real estate in Massachusetts?
The mortgage process can be intimidating, especially if you’re a first-time home buyer.

We’ve collected some of the most frequently asked questions buyers ask about mortgage loans to help you feel more confident. 

How do I know how much of a mortgage I can afford?

We recommend that your monthly mortgage payment be no more than 25% of your monthly take-home pay. Mortgage lenders will review your debt-to-income ratio to evaluate how much of your income goes toward all your current monthly debts. The lower the debt, the more you can borrow.

What’s the difference between pre-qualification and pre-approval?

Pre-qualification is a quick way to estimate how much you might be able to borrow, based on basic info you give me. It’s a good first step.


Pre-approval is more official. I’ll look at your credit, income, and finances to give you a more accurate number. Sellers usually take pre-approvals more seriously when you make an offer on a house.


Note: I’m always available to issue a pre-approval for your offer.
We will go over qualifications, mortgage programs, credit report and issue official mortgage pre-approval to you or your real estate representative.

It’s very important to start this early so we can work on any detrimental issues, get them resolved, and be ready and ahead of any other competitive buyers.

How does credit score affect a mortgage loan?

A credit profile is a record that shows how you’ve handled money you’ve borrowed in the past. It shows if you’ve paid your bills on time and how you manage your debts.


Your mortgage credit score, also called a FICO score, is a number based on different parts of your credit history. It comes from three credit agencies and can affect the mortgage rate you get — higher scores usually mean better rates.

How do mortgage interest rates work?

Your interest rate is what the bank charges you to borrow money. Lenders base it on factors like your credit score, the economy, and the type of home loan you choose. A small mortgage rate change can make a big difference in your monthly mortgage payment. 

What is “locking in” an interest rate?

Locking in an interest rate means your lender commits to a specified rate for a set amount of time. So, if rates increase before you close on your house, you’re protected while you finish the mortgage process.

What are the 2025 Mortgage Loan Limits?

What are “points” on a mortgage? 

Points are upfront fees you can pay to get a lower interest rate. One point usually costs 1% of your mortgage loan amount. It’s like pre-paying interest to save money in the long run. Whether it’s worth it depends on how long you plan to stay in the home.

What’s an escrow account after I buy a home? 

Your lender might set up an escrow account to collect money for property taxes and homeowners’ insurance. The lender adds this money to your monthly mortgage payment to pay those bills for you.

What’s the difference between a fixed-rate and adjustable-rate mortgage?

A fixed-rate mortgage has the same interest rate for the life of the loan. So your monthly mortgage payment is the same for the life of the loan.


An adjustable-rate mortgage (ARM) starts with a lower rate, but it can go up or down after a few years. ARMs can be good if you don’t plan to stay in the home long-term.

How do mortgage interest rates work?

Your interest rate is what the bank charges you to borrow money. Lenders base it on factors like your credit score, the economy, and the type of home loan you choose. A small mortgage rate change can make a big difference in your monthly mortgage payment. 

How much down payment do I need?

It depends on the type of mortgage loan. Some loans need as little as 3% down. If you’re a veteran or buying in certain areas, you might not need any down payment at all.

What’s PMI and will I have to pay it?

PMI is Private Mortgage Insurance. If you put less than 20% down, you’ll likely need to pay PMI each month. It protects the mortgage lender in case you can’t repay the loan. Once you build up enough equity, you may be able to cancel it.

Can I buy a rental property with a mortgage?

Yes. Buying a rental property usually requires a bigger down payment and a solid credit score. The mortgage rules are a bit stricter, but it can be a great investment.

When should I think about refinancing my mortgage?

Refinancing means replacing your current loan with a new one. Homeowners do this to get a lower mortgage rate, shorten their loan term, or take out cash. If rates have dropped or your financial situation has improved, it might be worth exploring.


Note: Typically, I recommend a No Points, No Closing Costs Refinance, which saves you money today and allows you to refinance again if needed. 

What’s a home equity loan and how does it work?

A home equity loan lets you borrow against the value of your home. You get a lump sum and pay it back over time, usually with a fixed interest rate. People use them for home improvements, big expenses, or debt consolidation.
