To reduce your risk of audit, you want to be sure the company you select uses the IRS' preferred method, engineering-based.

Some one preferably I can build a relationship with and they can help me as I grow my portfolio.

I'd prefer if you've worked with the contractors directly and can attest of their work!

Although I am still in my 20's myself, if I were to think back to when I was in college, I would probably prefer to be involved in real estate but not FULL IN.

Often the reason the sellers prefers cash is because of fast closing but more importantly not having to worry about low appraisals.

Personally, I prefer HELOC over refinancing.

Getting ahold of someone can be tricky sometimes but I want to hear it directly from them or preferably in writing. 

(There are several ways to address it)They're concerned their client will ask them for more information about seller financing, but they don't understand it themselves and don't want to appear uneducated.For these reasons, most real estate investors prefer to avoid an intermediary and speak directly with the seller.

I think your friend needs to contact a competent attorney in the state and preferably the county where the property lies for accurate advice as to if there is a judgement against the LLC and if it attached to the real property.

I would prefer in Ohio but wouldn't mind someone out of state as well.
