What Makes Up Your Monthly Payment?

What Actually Makes Up Your Monthly Payment?

Six variables. Six levers. One number on a listing doesn't tell the whole story.

Example scenario used throughout: $300,000 loan amount 6% interest rate 30-year fixed P&I = $1,800/mo

Rule of Thumb

per $1,000 loan

The shortcut:

Rate % ≈ $ per $1K
6% rate → $6/mo per $1,000
7% rate → $7/mo per $1,000

At ~6% market rate, a 30-year fixed mortgage on these loan amounts runs approximately:

$300,000 loan

~$1,800/mo P&I

$250,000 loan

~$1,500/mo P&I

$200,000 loan

~$1,200/mo P&I

Every $10,000 in loan amount = roughly $60/month difference in P&I payment.

The Six Variables

Each piece is controlled by something different. Know the levers, know your options.

Existing solar obligations on a property can affect loan qualification. A conversation for another day.

The Property Type Trap

Same loan. Very different payment. HOA is why.

Example scenario: $300,000 loan · 6% rate · P&I $1,800/mo · Same mortgage insurance

🏢 Condo — $300K Loan

Principal & Interest$1,800SAME

Mortgage Insurance$100SAME

Property Taxes$100

Condo Insurance$50

HOA Dues$300

Total / Month$2,350

🏠 Single-Family — $300K Loan

Principal & Interest$1,800SAME

Mortgage Insurance$100SAME

Property Taxes$150

Homeowners Insurance$100

HOA Dues$0

Total / Month$2,150

Same loan. Same rate. Same mortgage insurance. The condo saves $50 on taxes and $50 on insurance — but the $300 HOA costs $200/month more than the SFR.

That extra $200/month could support roughly $30,000 more in loan amount on the SFR. The same monthly budget that covers the condo payment could finance a noticeably higher-priced single-family home. Property type isn't just about price. It's about the full monthly picture.

Bonus Lever

Temporary Buydown — Lower Payment Up Front, Full Rate Later

Outside the six variables, there is one more tool. A temporary buydown uses seller-paid funds at closing to reduce the buyer's rate for the first one to two years. Using the same $300,000 loan at a 6% note rate ($1,800/mo P&I):

Year 1

~$1,432/mo

Save ~$370/month

Year 2

~$1,610/mo

Save ~$190/month

Year 3+

$1,800/mo

Full note rate

The seller funds the buydown at closing — typically around $6,700 on this scenario. That delivers ~$370/month in payment relief during Year 1. To get that same $370/month savings through a price reduction alone would require dropping the price by roughly $62,000. Same seller dollars. Very different result for the buyer.

The Real Conversation

Six levers. Real answers need real numbers.

🏷️

Purchase Price / Loan Amount

Every $1,000 in loan amount = ~$6/month in P&I. A $10,000 price change moves the payment by ~$60/month. Controlled by the market and the offer.

📉

Interest Rate & Loan Program

Rate determines the P&I. Program (conventional, FHA, VA) affects rate, mortgage insurance, and qualifying guidelines. Not one-size-fits-all.

💰

Down Payment

More down = smaller loan + lower or eliminated mortgage insurance. The right amount depends on reserves, closing costs, and monthly payment goals.

🏘️

Property Type & HOA

Every $100/month in HOA is equivalent to roughly $15,000 in loan amount at current rates. Property selection is affordability strategy.

🎁

Seller Concessions

Seller-paid concessions can fund a temporary buydown, cover closing costs, or reduce out-of-pocket cash. Almost always worth more to the buyer than an equal price reduction.
