How much credit can you have?

[Andre M.]

My wife and I own a house and we just bought a beach property. We did the beach condo as a 2nd home (I did it truthfully with the bank, and they know i am doing it as a STR...incidentally, they required I self manage if I wanted to call it a 2nd home). I am still very interested in the Smokies (working with Avery's team/Gennifer), but I would also need to do this as a 2nd home. I am not sure I can even call this a 2nd home when it is actually my third "home." Can I even have 2 vacation homes in addition to my primary residence?

But, to my original question, at what point do banks stop allowing me to borrow money, because I have borrowed too much? When I google search this, it just talks about credit cards. I know if I had a STR "business," they would let me use that income to borrow further properties. I do not, though. But since I am going for another vacation home, at some point, will they not pull the plug and say "nope. too much." My wife and I both work and have good income. I am sure that matters in whatever mathematical formula I am trying to find.

So finally, what is the formula to see how much money I am allowed to borrow?  I do not want to go through the whole process and then realize I am not a candidate for borrowing more.
