Security Deposits and Earnest Money in Real Estate Interviews
REPE and brokerage interview guide to security deposits vs earnest money: who holds cash, how it hits underwriting, and common confusions.
REPE · 5 min read
Security deposits and earnest money get searched together even though they live in different parts of a deal. Interviews reward clean separation. If you blur them, you look like you memorized a glossary instead of underwriting.
The short answer
"Earnest money is a good-faith deposit a buyer puts up under a purchase contract, often held in escrow, credited at closing or forfeited if the buyer defaults per the contract. A security deposit is cash a tenant posts under a lease to cover damage or default risk, sitting on the landlord's balance sheet as a liability until returned or applied. One is acquisition process. The other is leasing."
Why interviewers mix the terms on purpose
Both involve cash sitting somewhere temporarily, so juniors mash them into "deposit = protection." That is too vague. Earnest money protects a seller against a buyer walking after contingencies expire. Security deposits protect a landlord against a tenant defaulting on rent or leaving damage. Different contracts, different parties, different underwriting treatment.
Side-by-side
| Earnest money | Security deposit | |
|---|---|---|
| Who | Buyer in a purchase | Tenant in a lease |
| Purpose | Skin in the game to close | Protect landlord vs tenant risk |
| Typical home | Escrow | Landlord / property account |
| At success | Credited to purchase price | Held or returned per lease |
| Underwriting | Process risk and timing | Credit quality and liability transfer |
Acquisition contract tool. Size, hard vs soft, and extension mechanics tell you how serious the buyer is and how the diligence calendar works.
Lease credit tool. Size relative to rent and whether it is cash, letter of credit, or guaranty tells you tenant quality and landlord downside.
Earnest money: acquisition angles
In a purchase and sale agreement, earnest money is the buyer's skin. Soft money is often refundable if the buyer terminates inside a diligence window. Hard money is at risk after that window or after defined milestones. Extension fees can accompany more time. Interviewers care that you can narrate the calendar, not just the dollar amount.
Questions worth asking on a live deal or case:
- Who holds escrow and under what release conditions?
- When does money go hard?
- What happens on buyer default vs seller default?
- Is the deposit credited dollar-for-dollar at closing?
- Are there staged deposits as diligence clears?
For REPE interviews, earnest money is a process signal. A thin deposit on a competitive auction may mean less commitment. A large hard deposit after a short diligence window means the buyer already spent real diligence dollars and is signaling conviction.
Security deposits: leasing and sale angles
Security deposits sit as liabilities. On a property sale, they typically transfer with the asset so the new landlord inherits the obligation to return unused deposits. They can support a credit story for weak tenants, but they are not NOI and they are not a free cash pile for distributions.
Earnest
PSA process
Security
Lease collateral
NOI?
Never
How they show up in underwriting:
- Credit quality proxy when tenants are thin or new
- Working capital / liability true-up on sale
- Negotiation lever: higher deposit vs personal guaranty vs letter of credit
- Ops risk if deposits are poorly tracked on the rent roll
How the cash actually moves
Earnest path
Buyer wires to escrow under PSA terms. Funds stay restricted until closing credit, forfeiture, or refund per contract.
Security path
Tenant posts cash or LC at lease start. Landlord holds or holds via agent. Return or apply after move-out accounting.
Sale path
Buyer of the property typically receives a credit or assumption for outstanding tenant deposits so tenants are not left unprotected.
Model path
Keep deposits off the rent line. Track earnest in sources and uses / closing statement language, not in NOI.
Mini example you can say out loud
Buyer puts $500k earnest on a $25m multifamily PSA with a 30-day diligence period. After day 30 the deposit goes hard. Separately, the rent roll shows $180k of tenant security deposits. At closing the earnest credits to the purchase price. The security deposits transfer as a liability credit to the buyer. Neither number changes NOI. Only rent and recoverable income do.
Interview verbal and traps
Clean verbal:
"Earnest money is buyer deposit under a PSA. Security deposits are tenant lease collateral. I keep them separate from rent in the pro forma, I read refundability and release language on earnest, and I treat security deposits as a liability that usually travels with the asset on sale."
Common traps:
- Capitalizing deposits as if they were income
- Assuming every earnest deposit is nonrefundable on day one
- Ignoring letters of credit as substitutes for cash security deposits
- Forgetting deposit transfer mechanics in a sale sources and uses
- Mixing brokerage "deposit" slang without naming the contract
Follow-ups you should expect
| Follow-up | Clean direction |
|---|---|
| Is earnest money part of equity? | It is buyer cash at risk under the PSA; at closing it usually credits to the price |
| Do deposits help DSCR? | No. Lenders care about NOI and cash flow, not deposit balances as income |
| Soft vs hard money? | Soft is typically refundable in diligence; hard is at risk after defined triggers |
| What if tenant defaults? | Landlord may apply deposit per lease; still not a substitute for underwriting credit |
| LC instead of cash? | Same economic protection idea, different balance sheet presentation |
