Hi @Aaron Dyson congrats on the new contract. I love new construction for that very reason. At the end of quarters, months and years, they usually have some killer deals. Having to use their lender is annoying, but for someone who has done it before or at least knows it can be a frustrating process, it's worth it for the deal they give you.
Keep in mind comps can change in the 1-2 years you plan on living there. If you can tolerate it, go for the extra roommate. The biggest hurdle I have with convincing ppl to househack is they feel like they 'deserve' to live alone, they've put in the time with roommates in college, etc and they wanna feel 'grown-up'. But that extra $7200/year will go a long way in paying down your loan faster, build up another downpayment fund, pay off other debt, etc.
For new builds, get a third party inspection. The inspector should be thorough and telling you any issues. Since it's new construction, I hand the construction manager the full report and make sure they fix EVERY issue. It's a new home, so it should be as close to perfect when you buy it as possible. When you do the New Home Orientation, take your time and be thorough. Turn on faucets, showers, look at how the toilets are installed, are they wobbly, EVERYTHING. This is your one chance to change things. Take it. And make sure your Realtor is there with you as well, as they've likely done this dozens of times and know what to look out for.
For the LLC, talk to an attorney and your tax person. I've never been given a solid enough reason to put my properties in my LLC. So I'm guessing it might depend on your state laws and personal situation. and make sure you know of any sticky items that would eliminate the protection you get from the LLC. Lastly, know that any conventional loan likely has a 'due on sale' clause, where if you change the title of the property, they can call your note due. Some ppl find that's worth the risk, some ppl don't.
For managing properties, I have two options:
1. Hire a PM for the townhouse if you're doing a LTR and not a by the room situation. You already have a job, there's no need to give yourself another one. Delegating up front will help you open up brain space to expand and think about how to add to your portfolio, rather than running your portfolio.
2. If you feel passionate about managing them yourself, I'd recommend getting as much done and communicated up front. Make sure you have a solid lease, your tenant knows your expectations, how are you going to screen them, etc. Have a plan in place up front rather than trying to figure things out on the fly as much as possible. Especially for the roommate situation. Make sure everyone knows a cleaning schedule, expectation for common areas, how are you splitting utilities, guest policy, etc.
Hope this helps, and good luck on your journey!
