What to do when local comps are scarce for your cash offer

When local comparable sales are hard to find, you need to broaden your search criteria and adjust for differences. This involves looking further out and at different property types, then making careful adjustments.

Expand your geographic search

If the immediate neighborhood lacks recent sales, widen your search radius. Start by looking at properties sold within a half-mile, then a mile, then two miles, always prioritizing similar sub-markets. You are looking for areas with similar school districts, amenities, and socio-economic factors.

The further out you go, the more adjustments you will need to make for location variations. Be prepared to explain these adjustments clearly if you are presenting your valuation to a private money lender or a joint venture partner.

Widen your property type criteria

Sometimes, the exact property type you are comping (e.g., a specific style of ranch house) might not have recent sales. Look for sales of other property types that are common in the area and have similar bedroom/bathroom counts and square footage. For example, if you are comping a three-bedroom, two-bath ranch, but only two-story homes have sold, use those and adjust.

The key here is to find properties that a typical buyer in that area would consider an alternative. Avoid comparing completely disparate properties like a single-family home to a condo, unless that is the only data available and you have no other choice. In that case, your adjustments will be substantial.

Adjust for property differences

Once you have found comparable properties, even if they are not perfect matches, you need to make precise adjustments for differences. Factor in variations in square footage, number of beds/baths, lot size, age, condition, and any upgrades or deficiencies. For example, if your subject property has an extra bathroom compared to a comp, add a typical value for that bathroom to the comp's sale price.

These adjustments should reflect what a typical buyer would pay more or less for in that specific market. Use your experience with local contractors for repair estimates, and local agents for value adds. This is where your market knowledge becomes crucial.

Consider alternative valuation methods

When comps are truly scarce, you might need to supplement your valuation with other methods. A cost approach, which estimates the cost to rebuild the property minus depreciation, can provide a baseline. An income approach, if the property could be rented, can also give you a sense of its value based on potential rental income.

These methods are often used in commercial real estate, but they can inform your thinking on residential properties when traditional comps are missing. They will not give you a precise ARV, but they can help you establish a reasonable range.

Factor in holding costs and market trends

In a market with scarce comps, it is even more important to understand the broader market trends and your potential holding costs. Is the market appreciating, depreciating, or stable? How long might it take to sell this type of property? What will your property taxes, insurance, and utility costs be during that time?

A longer holding period directly impacts your profit margin. If you are uncertain about value, factor in a wider margin of safety. This means a lower initial offer to the seller to account for the increased risk and potential holding costs.

The honest truth about limited comps

When local comps are genuinely scarce, it means you are taking on more risk. You cannot be as precise with your ARV calculation, and your offer will inherently carry more uncertainty. Transparency with your cash buyers or partners about this lack of comparable data is key.

Sometimes, the best move is to pass on a deal if the valuation is too speculative. You are in this business to make money, not to guess. If you cannot confidently determine a value, it is often better to find another opportunity where the numbers are clearer.

Questions people ask

How far out should I look for comps?

Start with a half-mile, then a mile, and up to two miles if necessary, always trying to stay within the same market influences. The further you go, the more adjustments you will have to make.

What if there are no sales in the last year?

You might need to look at sales older than six months, but be aware that older sales require greater adjustments for market changes. You will also have to look further out or at slightly different property types.

Should I use a different property type if it's the only comp?

Only as a last resort and with significant, well-justified adjustments. Focus on properties that a typical buyer might consider comparable, even if they are not identical in style.

Is an appraisal worth it for a tough comp?

An appraisal can provide an objective valuation, but it adds to your cost and time. It might be worth it if you are struggling with a complex property and the deal has a high potential profit margin, or if a transactional lender requires it.
