Feel free to disagree or disregard a sappy do-gooder like me, but the more I understand real estate, the more complex it becomes.

I have a single member LLC (BV) that is owned 100% by a partnership LLC (ML) and is treated as a disregarded entity with all activity being reported on ML's 1065.

Be sure to look at your total yearly cost.Now are you talking about a Single Member LLC that will be Taxed as a disregarded entity on your 1040.ORa Multi-member LLC that will be taxed as a partnership with it's own return.OR An LLC taxed as an S-Corp with it's own return that will have to run payroll according to the state laws.You might get better protection having the operating agreement drawn up by an attorney due to wording in the operating agreement being more in your favor vs being silent and just reverting to State LLC law on certain issues.Also you have accounting to figure into the cost, will you need to produce IRS (and state) tax returns for it.Also, Also, some states make you pay a yearly "keep alive" fee.Also, also, also in some states a Single Member LLC might not offer as much protection as a multi-member LCC (another vote for using an attorney/specialist).Just my 2 cents.

However, you could us a "disregarded LLC" (a single member LLC that chooses to be taxed as a sole proprietor which means it doesn't file it's own tax return). 

I am having a hard time 1) knowing if my entity is a disregarded entity or not, so that I might buy in my own name (mixed messages from my CPA). 2) finding someone that might lend to my entity. 

Single member LLCs are disregarded entities for tax purposes.

Since typical LLCs are pass-through and essentially disregarded (especially SMLLCs) lenders aren't really bowled over impressed or eager to lend to an entity itself without personal guarantees.  

If you do not do this, you have a risk of fines, and, even worse, your LLC can be disregarded if it is involved in a law suit in a State that it is not registered to do business in.  

Most kids anyways want to go work to make money and don't want to be there or advance classes are disregarded by colleges and you have to repeat their version of that class. 

BP has lots of threads talking about entity selection.From a tax perspective, an LLC can be disregarded.
