I ran some quick numbers and would estimate (assuming you have good credit) you could borrow around $415k-$420k, which includes funding 100% of the rehab costs.Have you calculated your expected profit based on selling after rehab and if you decide to keep long term? 

If the students do not have the income or credit to warrant the rent amount, I would require that they get a cosigner (like a parent or another relative that can vouch for them).

sometimes to reduce borrowing costs, I'll use a hard money loan solely for the purchase, and then pay for the rehab in cash or use a 0% credit card (I don't recommend that for new investors!)

This also includes a few credit cards that are used for business expenses.

Check with a few local credit unions as they usually have the best HELOC offerings.

As I'm sure most of you know, a long-term rental is simple since the only recurring expense I own is the mortgage, whereas with a STR I'll own the mortgage, internet, utilities, furnishings, cleaning fees, etc. which just makes my projections a bit foggier.I'm looking for feedback on the below expenses and wondering what else I should be thinking about, that I don't currently have listed.

When a husband and wife jointly own a residence, and the husband takes out a Home Equity Line of Credit (HELOC) in his name only, the spouse's involvement and liability can vary based on several factors, including state laws and the lender's requirements.1.

Also, your DTI can sometimes be more flexible depending on your credit score or reserves, so it’s worth asking the lender about that.If your DTI is still too high, try looking at ways to lower your monthly payments or increase your rental income.

Next year i'll hit top pay and should start bringing in 1.2-1.3k a week. and the year after that i plan to move to linehaul and make about 2k a week.I do have a lot of debt, or at least it feels like it to me. the breakdown being;23k in college debt i got getting a bachelors that i never used across 5 loans ranging from 3 to 5% interest rate5k in bank loan debt i got getting my trucker cdl a at 12% interest rate.2.5k in credit card debt from not having an emergency fund and then having emergencies.

Depeding on the amount get a credit card that has no interest for 12-18 months.
