Can someone help me clarify this idea about buying multiple properties?

[Brandon Gamblin]

I might be having trouble trying to convey an idea about real estate investing. Maybe you all can help me clarify it? So here goes:

I understand that as real estate investors, we know that it's about buying in the right market, with the right strategy and with the right financing. I believe that is the baseline goal for every investor.

I've been scraping over Google and this forum for a post/thread or an article on an, “investor’s depth in their ability to buy” (Best way I can describe it). I’ve typed in terms/Keywords like, “Investor purchasing ability”, “Purchasing power of real estate investors' ' or “Property buying strategy for real estate investors”. I'm basically looking for something that glazes over or goes in depth about how an investor can set themselves up with as many options as possible to go about buying, but I can't seem to find anything.

To better explain what I'm trying to say, let me give some examples:

One investor might have his “buying artillery” or “buying depth” (still looking for a term to describe what I'm saying) as;
1. having a private lender and,
2. Being able to use conventional lenders.

Another investor might have;
1. $200,000 in cash sitting in the bank,
2. Some Type of partnership or a 50/50 LLC member ownership with his brother and can buy under that LLC because both of their credit scores are 700+, and
3. A hard money lender he can use.

How would we go about describing this and how can we teach and help other investors know their “purchasing ability”(If possible) and be able to “stretch” it as much as possible to “expand their ability to buy” as much property as their “buying artillery” allows them too?

Me, for example, being transparent, I only have the ability to use a hard money or private lender, but that is about as deep as I can go with my ability to buy right now until I can get my credit score up enough to get qualified for conventional funding too, if that's what I choose to do.

We know that the term "Buy Box" refers to an investors standard that could give him/her the green light on buying a specific property they might be looking at, if it passes that standard.

I believe that I'm lacking in the correct nomenclature and can't find the correct terms to describe this idea or concept that I'm trying to convey. Can someone come to a mutual understanding of the idea that I'm trying to express about having multiple or as many ways to buy property? I don't see it talked about enough. But maybe its because I'm not typing in the right keywords!

Is there a particular word for it?

And what are the best ways to set yourself to expand your “buying power” of properties?
