What are your thoughts on purchasing a SFH with credit? This would be using credit for the down payment rather than cash. For someone with limited funds up front, what are the negative impacts this can have, assuming you are able to make your payments on time each month and retain your current job?
Am I correct to assume the remainder of the purchase will be taken care of through a mortgage? It sounds risky to me to have to handle paying back a line of credit and a mortgage at the same time. How soon are you planning to pay the LOC back? Yes you may be able to handle the payments now. But as COVID has shown, a person's situation can change in the blink of an eye. Also, with you having limited funds upfront, how are you planning to handle emergency maintenance that may come up?
If you are getting a conventional or FHA loan, taking a loan for your down payment is not allowed and is one of the questions asked on the mortgage application. Don't risk mortgage fraud trying to get into a property.
