I have a legal business in the U.S. that has been open 1.5 years and I'm wondering if anyone has any good recommendations for a personal or business loan that will give me the best rate for this purchase? 

Purchase price: $116,000 Cash invested: $25,000 Personal home that will become a rental once fixed and updated or will be used for HELOC to purchase other properties on/off market at that time.

I can give you some advice that I learned from personal experience, and from also taking a BP course on multifamily.1) Are there any particular sub-markets within Orlando that are well-suited for small multi-family investment opportunities?

I don't recommend you bid on any as a new person.

It also stays off of your personal credit/DTI which will help you as you live your life outside of these properties.Those will be a specific set of lenders that you will want to look into as many of them have different requirements that you would have to adhere to, but overall much more of a simpler process than your conventional lenders, while being a couple of points higher in processing. 

Person B is the money-partner - will put up 100% of cash for the deal (ie. no financing).

There is both great cash flow and appreciation markets within ChicagoNow with all that said Chicago FOR SURE has it's challenges, but I have found personally that if I lean on #1, my network, that a lot of those high risks go away or can at least be mitigated.

When going into business regardless if it is RE or anything else it is wise to protect your personal assets. 

Regarding the LLC (let's call this Business B), my idea is to use the LLC to build business and corporate credit cards that I'm not personally liable for. 

Personally I prefer to invest locally to where I live.
