Why My Licenses Matter When You Sell Your House for Cash
Hey everyone, Juan Diaz here from Twin Home Buyer.
Most cash home buyers are investors who hire outside contractors to estimate repairs. That often leads to inflated costs and lower offers for sellers.
My approach is different.
Iβve been working in Bay Area real estate since 1985, and today I hold both:
General Contractor License
C36 Plumbing Contractor License
Because I handle repairs in-house, I can evaluate properties accurately and avoid the 20β40% markup many investors build into their offers.
For homeowners selling as-is, that can mean thousands of dollars in savings.
Why Accurate Repair Estimates Matter
Many investors lower their offers because they rely on rough repair guesses or expensive subcontractor bids.
When I walk a property, I personally evaluate issues like:
Plumbing leaks or outdated systems
Foundation or structural concerns
Unpermitted work or code violations
Electrical and mechanical systems
General renovation needs
After fixing thousands of homes over the past 40 years, I know exactly what these repairs cost.
That allows us to make fair, realistic offers instead of padded estimates.
No Subcontractors = Stronger Cash Offers
Most investors operate like this:
Seller β Investor β Contractor β Subcontractor
Each step adds markup.
At Twin Home Buyer, we eliminate those layers.
Because we handle many repairs ourselves, we avoid those additional costs β and that allows us to offer sellers stronger numbers upfront.
Why This Matters Even More in the 2026 Market
The Bay Area market in 2026 is selective.
Mortgage rates are around 6%, inventory is slowly rising, and buyers are becoming more cautious about homes that need work.
Weβre seeing:
Oakland median prices: ~$665Kβ$684K (down year-over-year)
Burlingame median prices: ~$2.57M (up around 3β4%)
Luxury and Peninsula markets still strong
Move-in ready homes sell quickly.
Fixer properties often face longer market times and heavy negotiation.
Thatβs why many sellers choose cash sales to avoid repairs and delays.
Real Bay Area Examples
East Oakland Plumbing Issues
A seller had major pipe failures and water damage.
Traditional buyers requested large repair credits or backed out completely.
Because I could assess the plumbing myself, we made a fair cash offer and closed in about two weeks. The seller avoided expensive repairs and months of uncertainty.
Burlingame Fixer Property
The home needed kitchen and bathroom updates plus yard cleanup.
Even in a strong market, buyers were hesitant because of the condition.
Our cash offer allowed the seller to skip repairs, showings, and negotiations and close quickly.
Inherited Oakland Property
A family inherited a home with outdated plumbing and electrical systems.
Instead of coordinating repairs and managing a listing, they chose a cash sale and closed quickly so the proceeds could be split among heirs.

Stress free process, paid all the closing costs and didnβt have to do any cleaning or repairs. Juan Diaz and team are men of their word. Very professional and respectful. The escrow process was a piece of cake. The best part is they close faster than any realtor listing the house ever could. If youβre looking for a no hassle way to sell your house quickly then I definitely recommend Twin home buyer and team.

The twin home buyer was awesome to deal with although they did not buy my house. They recommended me over to an amazing realtor that was able to get top dollar for my property. They let me know upfront that it was not the right match that they could not help me, but it didnβt stop there this company generally cares

I met with Juan Diaz on Saturday April 2nd and after showing him my property we sat down and discussed price. We finally agreed on a price that was not far off my asking. I felt strongly that Juan was genuine. He sent me a sale and purchase agreement that afternoon. I reviewed and had an advisor from HomeLight review it. The advisor said it was a "good agreement" and that it was "solid". I proceeded with the agreement on April 4th with up to 60 days to close. I may close sooner if I wish. Before meeting Juan I was dealing with two RE agents. One was great bit she overpromised the selling price, even when I presented her with contradictory comps. The other RE agent was pushy and persistent. Both agents wanted me to pour more money into the property. I felt that repairs and improvements were constantly draining my energy. What Juan gave me was a solution to my endless repairs and freedom from dealing with agents. He also alleviated my concerns by offering an Earnest Money Deposit of $50K. That's more than the standard $19.5K. He will also pay all the closing costs. All I would be responsible for is paying off the loan. I was almost immediately notified by the Title Company that the money was in Escrow. To sweeten the deal he also offered to have his guys move our stuff. I told him that I did not expect that but I definitely welcome it. Today someone dropped off 10 heavy duty boxes as I had requested. What more, there's is no need to clear out all of the junk that we accumulated over the years. That's a big help along with the 60 days. Moving is a stressful period in life and Juan made it that much easier. Now I will sit back and wait for an opportunity to buy again.

I had the pleasure of being contacted by one of the team members with Twin Homes. She was very pleasant to speak with and asked me to assist with the sale of one of their homes. She was prompt and available when I needed her. I later spoke with Juan Diaz who exemplified the values I stand for as a real estate professional. I have had such pleasant interactions with the entire team that I would always pick up the phone for them. If you have the opportunity to work on the buy or sale side I am sure you will be surprised with the communication and attention to detail they show. They have done the big and little things very well.
