Some require complete disclosure but some do not.

Full disclosure: I have not gone this route personally, and this is definitely a high-risk scenario. 

But it really depends on a number of factors.Full disclosure, I consult on this type of thing whether it’s for biz owners or RE investors for more estate planning type situations.

My specialty and focus is on buying sub to and you have to bring ALL your own docs, trusts, POAs, disclosures, how to add proper adendums to the purchase contract etc. 

If there’s no rules simply get it pumped and put the specifics you know about it on the property disclosure form when you sell.

If something goes sideways, I would be willing to bet 90% of these single owner LLCs formed for "asset protection" would be easily accused of piercing the corporate veil, and collapses the whole thing anyways.Depending on the state you are operating in, even if you use a Wyoming formed LLC, you will likely be required to register in the state you are operating in, which may require disclosure of that information you don't want to give up already - check to see what those states require for disclosures when registering a "foreign" LLC that is operating in the state.Literally no federal income tax benefits to where your LLC is registered. 

My buyers agents win a lot of deals with our model of providing a 24-hour loan commitment from the time an executed sales contract comes in, disclosures are signed and the buyers intent to proceed is completed.  

Full disclosure, the City of Detroit Assessor's office is not the best, so you often don't see as large as an increase as you should - but, there will be an increase!
