Sell vs Rent During a PCS to San Antonio: A Simple Financial Break-Even Analysis (With a Sample Spreadsheet)

by Mark Stillings

PCS season has a special talent for turning normal life into a speed run. One minute you’re staring at orders, the next you’re asking the biggest housing question of all: Do we rent or buy in San Antonio… and if we already own, do we sell or rent it out?

I’m Mark Stillings, Associate Broker, M.B.A. I’ve spent the last 18 years helping military buyers and sellers navigate San Antonio moves with less guesswork and fewer “well that was expensive” surprises. This post is built for high-intent searches like sell or rent PCS home, PCS financial analysis, and San Antonio rent vs sell—and it includes a break-even spreadsheet template you can copy.

Step 1: Understand the 2026 San Antonio “Rent vs Buy” backdrop

Before we do math, we need the market vibe.

Home values: Zillow’s Home Value Index shows the average San Antonio home value around $244,959, down about 3.1% year over year (timing matters if you’re selling, but it can also create opportunity if you’re buying). (Zillow)
How fast homes move / leverage: SABOR’s monthly reporting has shown a more balanced local market with months of inventory around ~6 and homes taking longer to sell than the peak frenzy period. That usually means buyers can negotiate more and sellers need better strategy. (sabor.com)
Rents: Redfin’s San Antonio rental trend page showed median rent around $1,245 (their charted period is March 2024, but it’s a useful baseline for the “rent side” of the equation). (Redfin)
National affordability gap: Realtor.com’s reporting has emphasized that in many metros it’s been more affordable to rent than buy recently—mostly because mortgage rates raised the cost of ownership. (Realtor)

So the decision is rarely “rent is always better” or “buy is always better.” It’s usually: Which choice wins for your timeline, monthly budget, and orders cycle?

Step 2: Rent vs Buy (PCS version): the 4 questions that matter most

1) How long will you be in San Antonio?

This is the biggest lever. Buying has higher upfront costs (closing costs, moving, potential repairs). Renting is more flexible.

A simple rule of thumb:

Under ~2 years: renting often wins unless you’re buying with a strong deal and low risk.
3–5+ years: buying often gets more competitive because you have time for equity + appreciation to work.

(And yes—this varies by price point, down payment, and interest rate.)

2) Are you using a VA loan?

VA loans can make buying more attractive because you may be able to purchase with 0% down and without monthly mortgage insurance (though you may have a VA funding fee depending on your situation). That reduces the cash you need to keep on hand during a PCS move.

3) What’s the monthly payment gap?

Don’t compare rent to principal+interest only. Compare rent to the real monthly cost of owning:

Principal + interest
Property taxes
Insurance
HOA (if any)
Maintenance reserve (even new homes need stuff)

4) What’s your “sleep-at-night” risk tolerance?

Buying sight unseen can be done safely, but it takes process. Renting buys you time to learn neighborhoods and commute patterns.

Step 3: If you already own a home: Sell vs Rent it out (PCS break-even)

This is where a lot of military families leave money on the table—not because they choose wrong, but because they don’t run clean numbers.

The sell vs rent decision comes down to two buckets:

Monthly cash flow (renting)
Net proceeds + opportunity cost (selling)

A) Renting: your “true cash flow” formula

True Monthly Cash Flow = Rent – (Mortgage + Taxes + Insurance + HOA + Management + Maintenance + Vacancy Reserve)

Common planning numbers:

Property management: 8–10% of rent (varies)
Maintenance reserve: 5–10% of rent (older homes trend higher)
Vacancy reserve: ~5% of rent (life happens)

B) Selling: your “walk away” number

Net Proceeds = Sale Price – (Mortgage Payoff + Closing Costs + Repairs/Concessions + Moving/Prep costs)

Then compare those net proceeds to what that money can do for you:

Pay down debt
Boost emergency reserves
Increase down payment (lower payment at the next duty station)
Sit in conservative investments until the next move

Realtor.com’s guidance on “sell vs rent” decisions emphasizes weighing carrying costs, landlord realities, and your local market conditions—because “being a landlord” isn’t passive if you’re 1,200 miles away. (Realtor)

Step 4: Sample PCS Break-Even Spreadsheet (Copy/Paste Template)

Here’s a simple layout you can drop into Google Sheets or Excel.

Tab 1: Rent It Out (Monthly)

Line Item	Example	Spreadsheet cell idea
Expected monthly rent	2,200	A2
Mortgage (P+I)	1,650	A3
Property taxes (monthly)	450	A4
Insurance (monthly)	180	A5
HOA (monthly)	60	A6
Property management (9%)	=A2*0.09	A7
Maintenance reserve (7%)	=A2*0.07	A8
Vacancy reserve (5%)	=A2*0.05	A9
True monthly cash flow	=A2-SUM(A3:A9)	A10

Interpretation:

If A10 is strongly positive, renting may work.
If A10 is negative, you’re paying to be a landlord (sometimes still worth it, but you’d better know why).

Tab 2: Sell It (One-Time)

Line Item	Example
Expected sale price	320,000
Mortgage payoff	265,000
Realtor fees + seller costs (est.)	24,000
Repairs / concessions (est.)	6,000
Net proceeds	25,000

Tab 3: Break-Even

Line Item	Example
Net proceeds if sold	25,000
True monthly cash flow if rented	150
Months to “earn back” selling proceeds	=25000/150 → 167 months

That last line is the “aha.” If it takes you 167 months (almost 14 years) of cash flow to match what you’d get by selling now, selling starts to look pretty good—unless you’re holding for other reasons (appreciation, long-term plan to return, etc.).

Step 5: The non-financial PCS factors people forget (but shouldn’t)

Landlord reality during PCS

If you rent it out:

Someone will call about the A/C… in August… on a Sunday.
You need a management plan and a repair reserve.
Remote ownership adds friction (and costs).

San Antonio market timing

A more balanced market (inventory around ~6 months) can mean:

Buyers may have more negotiating power
Sellers need stronger pricing + presentation
That’s not bad—just different. (sabor.com)

Your next duty station uncertainty

If you’re likely to PCS again quickly, flexibility has value. Renting in San Antonio for 6–12 months can be a smart “scout move,” especially if you’re unsure about commute gates, school zones, or whether you’ll extend.

Practical decision shortcuts (based on what I see locally)
