@Guillaume Vidallet I'll chime in here since it seems like everyone answered your question and gave some great advice.I'll suggest that whether you have one LLC or multiple LLCs you have separate bank accounts for each and make sure not to commingle any money.

While many of these issues are important considerations and should not be ignored or overlooked, there are other more crucial criteria that you must question and evaluate first.The critical risk criteria that you must review and evaluate prior to making your final decision on which 1031 Exchange Qualified Intermediary to retain includes, but is not limited to, the following areas:Technical capability of the 1031 Exchange Qualified IntermediaryInternal processes and audit controls to safeguard your 1031 Exchange funds and assetsUse of Qualified Trust Accounts or Qualified Escrow AccountsDecision criteria and guidelines for investment of your 1031 Exchange fundsProtection from potential errors or omissions by the Qualified Intermediary (E&O Insurance) Protection from potential theft or embezzlement of 1031 Exchange funds (Fidelity Bond) An experienced and professional 1031 Exchange Qualified Intermediary will understand these concerns and should be happy to discuss these crucial issues with you.

Especially if you cant 1031 and you have to pay recapture.Even with new construction this has to be taken into account..

However, I've learned a lot from that experience and am willing start over again- Make sure you stay on the top of them and fully account for the draws being taken as if they (Builder) have multiple projects I've seen where one individual's draw gets comingled with another property.

I'm new here and I have spent a couple of years studying real estate investing strategies.

My wife used to work for REM Wisconsin in accounting. 

Mainstream homeowner policies won't cover sober living because they don't account for the risk of multiple people recovering in the same home

And they should have accounts for everything with heavy discounts built in for their quantity buying.

Most start by analyzing deals and forget the fundamentals of every business, like getting a Tax ID, bank account later, Business Credit cards, and lines of credit.

This is only if I know or have studied under this person (*************, Ron Legrand  ect..).
