This is a CPA/Attorney question as stated well by others below.
My experience has been that if paying cash they can often enter the entity directly but with financing the property is purchased as an individual so you can get the loan and then title is moved into the entity. The loan has stayed personal to the individual in the situations I have been exposed to.
Again, very specific rules and regulations surrounding the scenarios that require the legal/CPA help so that you do this correctly.
The scope of LLC or Incorporation does not fall within the Real Estate License area of knowledge. I shared my experiences with others but yours may be different.
Yes you can. In AZ it doesn't change your liability to the lender just helps protect you..even then you would want to have your attorney or CPA talk to you about the other steps you would need to take.
All my investments are LLC's or trust.
Chat with your broker to get you a good referral.
If you are buying the property using a loan in your name and then you move the property into an LLC, you may
void the title insurance, you may trigger a due on sale or transfer clause in the underlying note, or other significant adverse consequences.
In order to know how to structure this type of deal, you need to consult an Attorney, a CPA, a Title Agent, a knowledgeable Finance and Real Estate professionals.
