Scaling with mortgages question

[Andrew Kennedy]

I keep reading stories where people start off with a property per year, then I hear people purchasing a property every month. Between a person and their spouse, they can only have a max of 10 mortgages. So what do people people do when they are scaling like that? Is there a limit on mortgages that a LLC can have? Do they have their LLC take on the mortgages? Do they take HELOCS to do all cash purchases? What if you're BRRRRing and you already have the mortgages capped and can't get another mortgage? Your BRRRR would be shot. So what do you do? Maybe bring a partner and leverage their credit? I know there are a lot of options but I'm curious as to what options you take. Thanks.
