I choose Satellite to look at what the neighborhood looks like.

Either partner with someone who can invest that money for you, or spend some time/resources getting up to speed on how to best go about jumping into any market you choose. 

Once you are tenants in common then you can sell properties and each of you can choose to do a 1031 or take the cash for the % of your respective sales.  

If you choose to have the on-site manager as an employee of your LLC, you gain direct control over their performance and alignment of interests, but you'll also shoulder management responsibilities and navigate legal and HR issues.

You chose your lender and you can also choose to find a new one, although it may cost you the deal and your earnest money. 

Articles of Organization (depending on the entity you choose), Statement of Authority, Operating Agreement (can be optional), Employer Identification Number (EIN).

Choosing a contractor who excels not only in construction, but also in clear communication, is the key to a smooth and successful project.

Some credit providers charge $50, some charge $200 and you don't have control over this unfortunately.Title fees: since you are purchasing, you probably didn't choose the title company, however this can be negotiated when you submit your offer.

What are the factors other than the interest rate when choosing between a Heloc or a cash out refi?

You can choose a 0 PPP which means you can sell or refi at anytime but the rates are higher.
