I think the fact that the numbers have to flush all the way through, the amount of variables, the number of subs, permitting, fire wall ratings, asbestos tests, lead tests, knob and tube wiring, walls not being square, projecting the ARV, market changes, and having it all cash flow at the end... is a lot to handle for most investors. 

Of course, between the units I will have a firewall, but the bedrooms and bathrooms I’m thinking what would be workable. 

Have a "firewall" (fire retardant drywall) all the way up between the units.2.

Amazon plumbing fixtures are really poor in quality.Amazon electrical fixtures are pretty decent.Amazon cabinet and door hardware is decent and better priced.We do LVP throughout the entire house.The firewall is not as intimidating as it may seem.

Depending on the circumstances, you may need to create a PSA to detail the transaction between the two entities if you're trying to keep the entities firewalled. 

.✔ It provides an extra liability firewall—the AMLP owns the LLCs, preventing direct lawsuits against you.✔ Keeps operations separate from property ownership—reducing legal risks from tenant disputes.✔ Strongest legal structure in Texas—LLCs roll up into the AMLP, keeping your name off public records.📌 Best Setup for Maximum Protection in Texas:1️⃣ Each rental property in its own LLC – Shields assets from each other.2️⃣ An Asset Management Limited Partnership (AMLP) – Owns the LLCs and manages them, keeping liability separate.3️⃣ Bridge Trust® for high-net-worth investors – If you scale up, this structure protects your entire portfolio from lawsuits.Final TakeawayWhile an LLC isn’t required to rent a property, it’s one of the best ways to protect yourself from lawsuits.

.🚫 “Common enterprise” concerns – If a single management LLC collects rent, signs leases, and maintains properties for all series, a court could argue there’s a shared enterprise, which might allow a plaintiff to target all series under one lawsuit.Better Alternative for Asset ProtectionA stronger structure that provides better legal separation and lawsuit protection is:1️⃣ Each property in a separate traditional LLC – This ensures clear separation and prevents legal issues with the Series LLC’s untested structure.2️⃣ Asset Management Limited Partnership (AMLP) – The LLCs should be owned by an AMLP, which acts as a liability firewall against creditors and judgments.3️⃣ A Bridge Trust® for maximum protection – If a major lawsuit occurs, the AMLP can be held by a Bridge Trust®, allowing assets to move offshore if needed.4️⃣ An operating LLC to handle management – Keeping rent collection and property management separate from ownership limits liability exposure.Why This Works Better:✔ Legally tested – Traditional LLCs have clear case law backing their liability protections.✔ No “common enterprise” risk – Since the AMLP, LLCs, and operating entity are legally distinct, it’s harder for a court to collapse them into one entity.✔ Protection beyond LLCs – If a major lawsuit occurs, the Bridge Trust® moves ownership offshore, making it extremely difficult for creditors to seize assets.Final Takeaway:A Series LLC has too many uncertainties for serious asset protection.

One thing Im personally doing is building some level of redundancy, firewalls, and silo'ing in my data management.

So, to the chagrin of some developers it can get a little expensive at times but on the flip side of that coin it provides kind of a firewall so that what ever is being built is being built with a strong intention.

@Daniel HymanThanks for the idea but another problem I have with using the government internet is a lot of things on websites don't work because of the firewall and network settings so when I try to apply for the account it just doesn't go to anything.
