Overview of How to Estimate Rehab Costs from Scratch (Materials & Labor) (Rookie Reply)
This Real Estate Rookie episode tackles three common rookie investor problems: what to do with a property that cash flows negative from day one, how to estimate rehab costs before buying, and how to make aggressive offers without derailing negotiations. Ashley Kerr and Tony J. Robinson focus on practical decision-making, emphasizing long-term strategy, realistic underwriting, and keeping emotions out of the deal process.
1) What to do when your rental is negative cash flow
The first question centers on a condo bought with a VA loan that now rents for less than the monthly payment, HOA, and related costs. The core debate: hold it and absorb the loss, or sell and redeploy the capital?
Main takeaways
-
Don’t judge the deal only on today’s cash flow.
Tony and Ashley both stress looking at:- future appreciation potential
- rent growth over time
- loan paydown
- overall investment goals
-
A negative cash flow property may still be worth holding if:
- the neighborhood is strong
- long-term appreciation is likely
- the monthly shortfall is manageable
- the investor can afford vacancies and repairs without strain
-
Consider alternative rental strategies beyond a standard long-term lease:
- rent by the room
- short-term rental
- mid-term rental
- government contracts / specialized rental uses
-
Run the full sell-side calculation.
Since the property was likely purchased with little or no money down, the owner may not have enough equity to sell without paying closing costs and agent commissions out of pocket.
Key decision framework
- What are your goals with this property?
- Can you comfortably cover the monthly gap?
- Is the market likely to support appreciation and rent increases?
- Would selling actually leave you with meaningful cash after transaction costs?
2) How to estimate rehab costs from scratch
The second question is about building a rehab budget for a BRRRR-style duplex, including materials, labor, and how to avoid over-improving for the neighborhood.
Estimating materials
-
Use Home Depot Pro tools and pricing if available.
Ashley points out that Home Depot’s rehab estimator can generate a materials list for specific rooms like kitchens, bathrooms, and bedrooms. -
Build your own rough materials estimate.
A practical DIY method is:- watch YouTube tutorials for a specific task
- identify required materials
- add them to a cart at Home Depot or Lowe’s
- use the cart total as a working materials estimate
Estimating labor
-
Call multiple contractors for quotes.
-
Some items are easier to ballpark than others:
- Easier: flooring, especially when stores advertise per-square-foot installation rates
- Harder: plumbing, electrical, HVAC, and more complex systems
-
Get at least three bids when possible.
- One may be very high
- One may be very low
- Two middle bids usually give the best read on market pricing
Avoiding over-improvement
-
Use local comps and pictures of renovated homes to understand:
- the finish level the neighborhood supports
- the rent ceiling
- how much buyer/renter demand exists for premium finishes
-
In lower-priced or rent-capped areas, upgrades like:
- granite countertops
- full tile bathrooms
- luxury finishes
may not increase rent enough to justify the cost.
Practical process
- Use online tools or store estimators to price materials.
- Get contractor quotes for labor.
- Walk the property with a contractor if possible.
- Compare your planned renovation to neighborhood comps.
- Only renovate to the level the market will actually pay for.
3) How aggressive offers should be structured
The final question asks how to submit a low offer on a property without offending the seller or wasting everyone’s time.
Main takeaways
-
Don’t fear “offending” the seller too much.
The hosts emphasize that sellers usually won’t be permanently turned off by one low offer. They may say no, but often they’ll still entertain future offers. -
Work with an investor-friendly agent.
Investors need agents who understand:- low offers are normal
- many offers will be rejected
- speed and volume matter more than emotional attachment
-
Use verbal offers first when appropriate.
Ashley recommends having the agent talk to the listing agent before writing a formal offer to:- gauge interest
- learn seller motivation
- avoid unnecessary paperwork
-
Follow up consistently.
If a seller rejects a low offer, the door may still reopen later if:- the listing sits
- price reductions occur
- the seller becomes more motivated
Mindset shift
- The listing price is not sacred.
- Sellers may be flexible, especially if a property has sat on the market.
- Low offers are part of real estate investing, especially for BRRRR-style buyers looking for margin.
Key lessons from the episode
For new investors
- Real estate decisions should be made from a long-term financial strategy, not short-term emotion.
- A deal that looks bad on monthly cash flow may still be strong when appreciation and tax benefits are considered.
- Rehab budgets should be built from real material estimates + multiple labor bids, not guesses.
- Aggressive offers are normal in investing; the key is being professional and persistent.
Best practices highlighted
- Calculate true holding costs before deciding to keep or sell.
- Compare all-in rehab costs to local market rents and resale values.
- Use comps to guide finishes and avoid overbuilding.
- Make offers confidently, then follow up respectfully.
Action items for rookies
- Run a full hold-vs-sell analysis on any negative cash flow property.
- Check equity after selling costs before assuming a sale will free up capital.
- Use a rehab estimator or DIY cart method to build materials budgets.
- Get 3 contractor bids for major labor items.
- Study neighborhood comps to avoid over-improving.
- Work with an investor-friendly agent when making low or aggressive offers.
- Follow up on rejected offers instead of assuming the deal is dead.
Notable insight
A property can be a “bad” cash-flow deal and still be a good investment if appreciation, rent growth, and loan paydown make the overall return worthwhile.
