You can remove a link and get a better picture of the seller going straight to their agent.Joseph is correct. 

I jumped straight into multifamily in order to have an easier time finding a positive cash flowing property.

Even hard money and private lenders will require the borrower to have cash in the deal, assuming you are talking about flipping/rehabbing and not straight wholesaling.If you only intend on wholesaling, you only need enough for a handful of earnest deposits to be sitting out at any given time, and likely won't ever need a lender, since you will never be purchasing the properties.

The land trust is beneficial because it masks what is going on behind the scenes with the assignment of beneficial interest; however, it is not as straight forward as the LLC purchasing the property and some sellers get confused. 

--If you can afford to go straight into multifamily, the economies of scale in this category make it much easier to generate initial cash flow.

Everything else with the property is relatively straight forward - new kitchen, new bathroom, refinish floors, and paint.My question is whether I'll need to fix the foundation issues with the garage in order to pass an FHA inspection, especially since it's not part of the main 'structure'. 

Straight to the point summary:I'm about to purchase a 3-4 bed & 2-4 bath house in Orange County area.

Depending on how much the wall is delecting, it can be stabilized or replaced, both is relativley straight forward.

I think it's always a good idea to check out the straight-up Chicago Investor Podcast @Mark Ainley has a ton of great guests on there.  

Your letter should be straight to the point and basically tell them you are willing to overpay for the opportunity to buy their home off-market and they will also save on realtor fees on their end.
