Summary of Build vs. Buy: Which Is Best for Your First Rental?

Overview of Build vs. Buy: Which Is Best for Your First Rental?

This BiggerPockets Q&A episode focuses on practical decision-making for real estate investors, especially first-time buyers and house hackers. Dave Meyer and Henry Washington answer forum questions about whether to build or buy a rental, how to evaluate older homes, how detailed rehab budgets need to be for lenders, whether house hackers should hide ownership from tenants, and how to safely work with wholesalers. The recurring theme: good deals are less about avoiding risk entirely and more about understanding and underwriting it correctly.

Build vs. Buy for a First Rental

The first question comes from an investor considering building a duplex for a first house hack using an FHA construction loan.

Main takeaways

• Building can work, but it’s usually not the best first move unless you already have:
  • Construction experience
  • A strong contractor team
  • Adequate funds
  • Time to wait for completion
• New construction can offer benefits, but execution complexity is high:
  • Finding land, plans, engineers, and lenders
  • Managing delays and cost overruns
  • Potentially creating a product that may not rent well in that market

Market fit matters

• If a market has very little multifamily inventory, that may signal low renter demand for multifamily product.
• Dave and Henry suggest considering:
  • A different market
  • A different strategy
  • Buying existing rentals instead of building a custom product that may be hard to lease

Practical recommendation

• For a first deal, they lean toward buying an existing rental rather than building from scratch.
• In smaller markets like Oxford, Alabama, they suggest looking at nearby markets with stronger rental ecosystems instead.

Buying Older Homes: What to Inspect First

A second question asks whether investors should expand their buy box into pre-1960s homes and what risks to watch for.

The “big five” systems

Henry recommends always inspecting:

• Plumbing
• Electrical
• Roof
• HVAC
• Foundation

Biggest risks in older homes

Foundation

• Especially problematic in the Midwest and homes with old cinder block foundations.
• Foundation repairs can cost tens of thousands of dollars and still leave a house slightly uneven.
• Even repaired homes can be hard to resell if they still look compromised.

Plumbing

• Replacing old plumbing can become extremely expensive.
• Dave mentions a full replumb costing around $80,000.
• Plumbing issues can become a long-term owner burden in buy-and-hold properties.

Electrical

• Knob-and-tube wiring is a concern, but electrical upgrades are often more manageable than plumbing or foundation.
• Henry estimates full electrical replacement can be roughly $5,000–$10,000 in many cases.

HVAC

• Older homes may have boilers or no ductwork.
• Adding modern heat and air can become expensive, especially if the house has never been ducted.
• Costs can jump significantly when you need to install full duct systems.

Key advice

• Don’t buy an older home just because it’s cheap.
• Buy older homes only if:
  • The foundation is sound
  • The plumbing is modern or manageable
  • The layout works
  • The property has been renovated recently enough to avoid major hidden systems work

Best construction era

Henry’s preferred “sweet spot” is roughly the early-to-mid 1970s:

• Fewer knob-and-tube issues
• Better layouts and larger rooms
• Good build quality compared with some modern construction
• Still old enough to often offer value

Dave adds that 1960s and newer can also be attractive, especially if the property has already been upgraded.

How Detailed Should a Rehab Budget Be for Lenders?

An investor asks how granular a rehab budget needs to be for hard money, private money, or renovation loans.

Henry’s approach

• He uses a detailed internal budget for underwriting.
• But when submitting to lenders, he provides a high-level rolled-up version.

What lenders typically want

A lender-ready budget usually includes broad categories such as:

• Flooring
• Interior paint
• Roof
• HVAC
• Plumbing
• Electrical
• Appliances
• Contingency

Why this works

• It shows the lender you have a real plan without making the process overly cumbersome.
• It also aligns with the work investors should already be doing when underwriting a deal.

Advice for newer investors

• Expect more scrutiny if you’re new.
• Be ready to show:
  • Multiple quotes
  • Clear contractor plans
  • Realistic assumptions
• If a lender pushes hard on reasonable details, that may be a sign they’re not a great fit.

House Hacking a Duplex: Should Tenants Know You’re the Owner?

Another question asks whether a house hacker should hide ownership and present themselves only as a property manager.

Dave and Henry’s view

• They both recommend being transparent and not overcomplicating the relationship.
• Henry admits he used to say he had a partner or acted like a manager, but says he would not do that today.

Why transparency is better

• It avoids unnecessary confusion or distrust.
• Tenants may actually take better care of the property if they know the owner lives nearby.
• Honest communication sets the tone for a better landlord-tenant relationship.

Suggested approach

• Be clear that:
  • You want the property kept clean and in good condition
  • You’ll take care of legitimate repairs
  • Rent should be paid on time
  • If issues come up, communicate early

Core lesson

The best house hacking strategy is usually direct, respectful communication, not creating an artificial separation between owner and tenant.

Should You Work With Wholesalers?

The final major question covers whether investors should buy from wholesalers or avoid them.

Main answer

• Yes, you can work with wholesalers, but you need to do your own due diligence.
• Bad wholesalers exist, but bad operators exist in every real estate category.

How to evaluate wholesaler deals

Henry’s key rule:

• Treat the wholesaler’s price, ARV, and rehab estimate as irrelevant starting points
• Only use the property address to do your own analysis

Questions to ask wholesalers

• Are you in direct contract with the seller?
• How many deals have you done?
• Which title company closed your prior deals?
• Can you share the original contract before signing an assignment?

Legal and contract risks

• Watch out for wholesalers who:
  • Don’t actually have the property under contract
  • Misrepresent the deal
  • Engage in questionable assignment or “daisy chain” arrangements
• Always review the original contract so you understand your obligations before signing an assignment.

Dave’s takeaway

• Don’t worry about whether the wholesaler is making money.
• Focus on whether the deal works at your price.
• If it does, the profit split doesn’t matter.

Overall Takeaways

For first-time investors

• Keep your strategy simple.
• Buying an existing rental is usually easier than building a custom property.
• Avoid overcomplicating your first deal with construction risk.

For older homes

• Older doesn’t automatically mean bad.
• But you need to inspect the systems that can create major losses:
  • Foundation
  • Plumbing
  • HVAC
  • Electrical
  • Roof

For financing and rehab

• Lenders generally want enough detail to trust your plan, not an exhaustive line-item essay.
• A clear, organized budget is usually enough.

For tenants and wholesalers

• Transparency and trust matter more than image management.
• With wholesalers, your responsibility is to verify the deal, the contract, and the numbers yourself.

Practical Action Items

• If considering a build-to-rent first deal: compare it against buying an existing rental in a nearby market.
• If buying older homes: hire specialists for foundation and plumbing inspections.
• If preparing rehab budgets: create a detailed internal budget, then simplify it for lenders.
• If house hacking: be honest with tenants and establish expectations early.
• If working with wholesalers: verify contract structure, title history, and perform independent underwriting.
