How much should you spend on renovating a house
There isn’t a one-size-fits-all formula for calculating the exact amount you should spend on a house renovation to ensure a profit, as this depends on various factors including the property’s current value, the current market conditions, the nature of renovations, and the specific area in which the property is located.
However, a commonly used guideline in property development is the “70% Rule,” which is particularly popular among property investors, especially those involved in “flipping” houses (buying, renovating and reselling in a short timeframe) .
What is the 70% rule
The 70% rule states that an investor should not pay more than 70% of the After Repair Value (ARV) of a property minus the costs of the repairs needed:
Maximum Purchase Price=ARV×70%−Repair Costs
Maximum Purchase Price=ARV×70%−Repair Costs
Where:
- ARV (After Repair Value) is the property’s estimated value after all renovations are completed.
- Repair Costs are the estimated total costs for all the necessary renovation work.
Example Calculation:
- Determining the ARV: Research comparable properties in the area that have recently sold and are in a condition similar to what your property will be after renovations. For example, if you determine the ARV to be £300,000, that’s the expected market value of your property post-renovation.
- Estimate Repair Costs: Get quotes or estimates for all the planned renovations. Suppose this amounts to £50,000.
- Apply the 70% Rule:
- Maximum Purchase
- Price=£300,000×70%−£50,000=£210,000−£50,000=£160,000
So, according to this rule, to make a profit in this example, you should not pay more than £160,000 for the property before renovation. If you already own the property you can reverse engineer the numbers to work out how much you need to spend using the current market value (pre work) and the estimated value (post work) this would give you a rough guide as to how much you can spend on the renovation before it becomes financially unviable.
Important Considerations:
- Local Market Variability: The 70% rule is a general guideline and may need adjustment based on local market conditions. In some markets, you might need to adjust this percentage lower to be competitive.
- Accuracy of Estimates: The accuracy of your ARV and repair cost estimates is critical. Underestimating costs or overestimating ARV can lead to lower profits or even losses.
- Experience and Skill: The rule is more effective if you have experience in renovations or a good team of contractors who can work efficiently and cost-effectively.
- Market Trends: Be aware of current property market trends and future predictions, as these can significantly impact your ARV.
- Additional Costs: Don’t forget to account for additional costs such as holding costs, financing costs, transaction fees, potential taxes and sale fees such as solicitor and estate agent fees.
This rule is a starting point and should be used alongside thorough market research and professional advice, especially if you are new to property investment or the property market is particularly volatile as it is at time of writing.
