155,000 Loan On Property

[Frankie Betancourt]

Hello i bought a house for 75000$ and can get a loan on it for 155,000$  My question is hypothetically if i were to only get a 20,000 Loan From the 155,000$ loan and never pay it would they foreclose on my property and i would loose it for not paying the 20,000 Loan?

Also Lets Say i take out the 155.000$ Loan and never pay it would it be like selling my house where the lender keeps my house as collateral for non payment Or do i loose my House and have to pay back the lender155,000$ that i barrowed?
