Hard money loan question

[Kacper Rajewski]

Ok so what is the logic behind the hard money? Let's say that i have a house to rent and the numbers are there and i cash flow lets say 500$. What if i wanted to buy another house...? And another. And another. And another. And... Is there's limit to where i can borrow money and they just don't care that i did my Excel spreadsheet and it turned out that there will be profit from that house? As far as i understand the loan is given against my asset and not against my credit right? The rates on the hard money loans are high so is there's even a possibility on making any profit?
