I believe Alexandria city allows it but portions of Fairfax county do not allow it. i would go option 1 personally. 

@Jason Lopez You don’t need an LLC to rent out a house in San Antonio, TX, but it can provide liability protection by separating your personal assets from your rental property.

I would build a relationship with the person before you decide to partner.

Liability Protection: An LLC provides legal separation between your personal and rental property assets, which can protect personal assets if a lawsuit arises.

It would just need to be a situation where they have great contact with the person doing that managing of the project (I.e. have known the person for years, great reputation, person has experience in flipping etc.).

You will quickly find, as you generate local person-to-person relationships, how many opportunities open up! 

Personally I am thinking 1c.

I recommend using a lender that non-reporting to personal credit and can close under the LLC to keep your DTI lower and overall your personal liability profile more bankable.

Quote from @Leonard La Rocca III: So is it common to find a conventional loan without meeting the lender in-person?

So is this just as simple as showing how much the property makes or do they also look at personal debt to income, credit score, reserves etc as well.
