# Gross Annual Value (GAV) — Special Cases
The basic GAV rule is `GAV = Higher of (Expected Rent, Actual Rent net of unrealised rent)`. However, special situations modify this rule. Learn each scenario individually because the treatment differs.
## (i) Deemed Let-out Property
A deemed let-out property is one which the assessee could let out but is treated as if let out under the law (e.g., when the assessee owns more than 2 self-occupied houses, the additional ones become deemed let-out).
- Since there is no actual letting, Actual Rent (Step 2) = 0.
- Therefore: GAV = Expected Rent (Step 1).
- Expected Rent itself = Higher of (Municipal Value, Fair Rent), but restricted to Standard Rent (if any).
## (ii) Let-out Property which is Self-Occupied for Part of the Year
If a property is partly self-occupied and partly let-out during the same previous year (sequentially in time, not in area), no adjustment is made for the self-occupied period. The standard comparison rule (Higher of Expected Rent for the full year vs. Actual Rent for the let-out period) applies as usual.
## (iii) Let-out Property which is Vacant for Part of the Year
This is the trickiest case. Compare `Actual Rent (Step 2) + Vacancy Rent` against `Expected Rent`:
| Comparison | GAV |
|---|---|
| (Actual Rent + Vacancy Rent) ≥ Expected Rent | Actual Rent (Step 2) — vacancy benefit reduces GAV |
| (Actual Rent + Vacancy Rent) < Expected Rent | Expected Rent (Step 1) |
The logic: if the property would have fetched the Expected Rent had it not been vacant, the assessee gets the benefit of vacancy and pays tax only on Actual Rent.
## (iv) Partly Let-out and Partly Self-Occupied (by Area)
When part of the house is let out and another part is self-occupied (e.g., ground floor let out, first floor self-occupied):
1. Treat the two portions as two separate properties.
2. Divide all figures in the area/portion ratio — Municipal Value, Fair Rent, Standard Rent, Municipal Tax, and Interest on Loan.
3. Do NOT divide Actual Rent — it relates only to the let-out portion.
4. Compute income separately for each portion (one as let-out, one as self-occupied).
