The way I'm using build-to-rent right now is to create deals instead of competing for them. Instead of fighting other investors over listed properties, I'm adding density to lots that already exist, the same strategy I lay out in hidden density: create deals instead of competing for them. It works, but it comes with a real cost: building means you live in the zoning code, you need site plans, and you need estimates from a dozen different trades before you can even pencil a project.
That's where technology earns its keep. Roughly 2% of investors ever get into this strategy, and the paperwork is a big reason why. Here are the tools I actually use to cut that work down. Most of them cost less than a dinner out.
NotebookLM for Living in the Code
I'm absolutely obsessed with NotebookLM. If you have a paid Google account, you already have access to it for free.
A huge part of building is understanding the local jurisdiction's zoning code, and reading raw municipal code is miserable. So instead, I create a separate NotebookLM notebook for each municipality I'm building in. The tool pulls in whatever sources you feed it: the zoning code PDFs, text documents, even YouTube content. Then you can chat with it, and it answers your questions based only on the knowledge base you gave it. It's a different use case than how I use the same tool for company SOPs in turn your scattered SOPs into a living company wiki, but the underlying trick is identical: feed it the source of truth, and stop guessing.
A real example: on one of my projects I needed to know if there was a maximum building height for a specific business district. I didn't want to dig through the whole code, so I just asked the notebook, and it answered instantly, grounded in the actual code I had loaded.
It takes me about 15 minutes to set up each notebook, and I do one per municipality. It saves an enormous amount of time, and it's the first tool I reach for on any new build.
Google Earth and Rayon for Site Plans
Every morning I go through the new listings and price reductions, and the very first thing I do is pull up the overview map and look at the lot. Google Earth is my first-pass screen: does it have alley access, where are the water setbacks, is there room in the backyard for a detached unit or two.
Once a lot looks viable, I need a site plan, and I don't want to wait on a surveyor or planner to draw one up. We use Rayon for that. It quickly overlays plans, works with CAD and a lot of other file types, and has a multiplayer mode a bit like Figma, so my team can work in it together. It's fast for drawing up site plans in house.
The reason a site plan matters so much: anytime you're meeting with the city or county about what you want to build, showing up with a site plan gets you far better answers, because they're looking at exactly what you're looking at. On a recent deal the city flagged that we needed a 10-foot setback for an existing sewer line, and because we had the plan up, we adjusted it right there and confirmed the project still fit, a version of the same lesson I learned the hard way in always scope the sewer line.
Rayon runs about $10 to $15 a month. For what it saves in surveyor and planner time, it's one of the easiest yes purchases in my whole stack.
Perplexity Plus Airtable: The 17-Bid System
This is my favorite one, and I can't take credit for it. My director of operations built it to solve a specific pain: on a build, you need estimates from a lot of different people. Planners, surveyors, civil engineers, structural engineers, drafters, architects, insulation, foundation, all of it. Chasing those bids one phone call at a time is brutal.
The old way nearly broke me. On an earlier project I needed mini-split quotes, and it took me two hours of calls with HVAC contractors, all of them asking for plans, endless back and forth. My ops lead said he had a better way, and he built this, a good example of what the right hire can do once you get out of the way, which is the whole argument in hiring a remote team: VAs and integrators.
Here's the workflow:
- Use Perplexity to find all of the relevant vendors in the area you're building in.
- Load them into Airtable.
- Airtable sends a templated email from our company Gmail, with the site plan or building plans attached (you can attach photos and video too).
- It goes out to the whole list at once.
- Responses come back and stay organized in Airtable, so you can shortlist your top five and keep their historical bids for future projects.
We put this to work on structural engineers and reached out to 17 of them. Quotes came back fast, ranging from as high as $8,000 down to $2,300 for the same scope. The part that still gets me: sending all 17 took about five minutes. Airtable costs us maybe $100 to $120 a year, and it connects straight to our company Gmail.
Once you've run this a few times, you stop starting from scratch. You go back to your top five vendors, look at what they bid last time, and move. If you want to see how those bids actually compare against real project costs once you're building, estimate every operating cost before you offer and real numbers from 4 of our build-to-rent projects both walk through the numbers on our own deals.
Drafters Over Architects (When You Can)
This is not a software tip, but it saves more money than any tool on the list. For most projects under four units, you can use a really good drafter or designer instead of a licensed architect.
My process is simple. I go online, find four plans I like, send them to my drafter, and tell him what I'm thinking. About 24 hours later I get a full draft back. My last set of plans came back in four days. You still need a separate structural engineer for the calculations, but the plans themselves don't require an architect if it's not required by code.
The savings are not small. We paid a designer $450 for building plans that licensed architects were quoting me $9,000 for. Same plan. People assume they have to use the architect, and a lot of the time they simply don't.
Put It Together
None of these tools replace the work of talking to a lot of people, walking a lot of lots, and knowing your numbers. What they do is compress the busywork so you can actually run this strategy without a full development team. NotebookLM to live in the code, Google Earth and Rayon to see and draw the lot, Perplexity and Airtable to get your bids in minutes, and a good drafter instead of an architect where the code allows it. Once the tools have done their job, the financing has to hold up too, which is the piece I cover in how to finance a build without touching your low-rate mortgage.
I'm a systems and efficiency person at heart, and this stack is how I make build-to-rent workable as an investor rather than a full-time developer. If you want to see how we approach creative deals and the referral side of our business, come find us at Agents Invest.
FAQ
Q: What AI tools do you use for real estate development? A: NotebookLM for researching zoning code by municipality, Perplexity for sourcing contractors and vendors, and Airtable to organize and mass-send bid requests. Rayon handles site plans, and Google Earth is my first-pass lot screen.
Q: How do you get contractor bids quickly? A: We use Perplexity to find vendors, load them into Airtable, and send a templated email with plans attached from our company Gmail to the whole list at once. On one project we sent requests to 17 structural engineers in about five minutes and kept every bid organized for future comparison.
Q: Do I need an architect to build a small rental? A: Often no. For projects under four units, a strong drafter or designer is usually enough, with a separate structural engineer for the calculations. We paid $450 for plans that architects were quoting at $9,000. Always confirm what your local code actually requires.
