@Taylor Georges welcome to the forums you bring some great experience to add value so I look forward to seeing your posts.  

The comments above are great examples.2-20 units+ comes down to a lot of different options. 

If, for example, you're looking at a larger, commercial deal with or without partners, it would make sense to have a separate LLC for that property. 

For example, if they really want $500k for a property, maybe offer a purchase price of $500k but a lower down payment and interest rate (and a longer-term).

Ive owned property before so its not super scary to me, but I am far from experienced enough to see the intangibles that may cause problems down the line.

There are costs that you are likely paying for, at least temporarily, to get this all rolling, but net effect is "no money down" for the GP.You could get your rich parents to loan you money from your inheritance, which is "no money down" for you...But, what I think you are actually getting at is, like your example, "how do I get started with little to no money?" 

If you have been to these towns, they are good examples but very difficult to enter and make money from. 

You can check Google/finance to see if they are profitable or NOT.I would also suggest not targeting the cheapest brokerages. 

Do shop around though and see what you find!

Boring businesses usually do best, for example .. you can clean or service boats.
