For now I'll concentrate on rehabbed 3 to 6 flats in stable communities but I don't see too many on the market that's within my price range. 

--What is the average interest rate (or range) that lenders charge? 

That is a big range on the repairs.  

These are just out of, or are completely out of my price range.  2.

I have several guns and dozens of hours at the range.

I understand that it is a very big range, but I want to remain open to any niche until I find the right deal.I look forward to meeting some people!

I'm guessing you're looking at rents in the $650-750 range for that price.

We are looking for something that wouldn't be more than a 20 minute bike ride to the beach around the 100k range.

But I don't know how many times I have heard "we didn't know about the house but the beautiful landscape did it for us" or "This house was way above our price range but we got it anyways because of the landscape." so my question is, to professionally or not to design?

There's nothing like total immersion to become Baptized as a landlord IF you're willing to tackle the tasks at hand.Here's what you'll need to do in short order:Crash course on landlord/tenant laws in your stateSet up (separate) systems for marketing for target tenants, screening/vetting prospects, easy rent collection, bookkeeping, contractor/handyman management, etc.The three best educational resources I can offer:Fixer Jay Decima, of 'Tenants & Toilets' fame (lower-end), Mike Cantu for mid-range tenant management, and David Tilney for the higher end of the market.
