## Section 23 — Computing Gross Annual Value (GAV) of Let-Out / Deemed Let-Out Property
GAV is the foundation of HP computation. It is the higher of Expected Rent and Actual Rent received/receivable.
### Three-Step Procedure
#### Step 1: Compute Expected Rent (ER)
> ER = Lower of:
> - Higher of Municipal Value (MV) and Fair Rent (FR)
> - Standard Rent (SR)
Expressed as a flow:
```
MV ┐
├→ Higher → A ┐
FR ┘ ├→ Lower → Expected Rent
SR ───┘
```
#### Step 2: Compute Actual Rent (AR)
> AR = Actual rent for the let-out period − Unrealised rent (if conditions of Rule 4 satisfied)
#### Step 3: GAV
> GAV = Higher of ER and AR
### Definitions
1. Municipal Value: Rent as per records of local authority.
2. Fair Rent: Rent of similar property in same locality.
3. Standard Rent: Maximum legally recoverable rent under Rent Control Act.
### Important Timing Rule
- MV, FR, SR → always taken for the full 12 months of the PY.
- Actual Rent → taken only for the actually let-out period (whether received or receivable).
### Unrealised Rent — Conditions (Rule 4)
Unrealised rent can be deducted from actual rent only if all conditions are satisfied (genuine tenant, vacated/legal action taken, etc.).
