Currently my credit is under 515, I know I can fix it but need more income and cash.

I think they've really been helped by the full/partial telecommute, as it's not terrible if you had to go into the city once or twice a week, but if everyone goes back to full-on 5 day offices I think there will be some exodus. 

You might check with smaller outfits too like Co/Lab lending, Preferred Mortgage, Aceland Mortgage, and co-ops/credit unions.

Would be interesting to hear experiences others have had..The expectation for rent being used to help build credit has slowly grown over the years.

They're good to have open access to capital/cash/equity to a property ahead of time so you can execute a deal or purchase when the time comes on a split second decision (versus having to apply to a loan at that time which might take 20-45 days to get approved/closed/etc plus by that time you dont know what your future income/credit/assets will be like in order to qualify anyway).The second use is sleep at night factor and having a reserve of capital in the event an emergency event occurs in life.For these two reasons is why I use lines of credit.

There are some lenders that require a deposit up front and is credited at closing for fees.

Credit, Criminal, and eviction seemed fine.

I will also be tracking expenses related to repairs, maintenance, travel to and from NV, hotel stays, meals, gas, and other regular business costs.In the long term, I aim to purchase additional properties under the business name, but I understand I need to establish at least two years of income and credit history before doing so.The issue I’m encountering is that my accountant has not provided any guidance on how to structure this scenario.

Not sure if these are all investment properties or if you're including a primary or second home, but my suggestion would be a cash out refi of an investment property to pay off your debt, and a line of credit on your primary to have available for reserves if needed.

Your credit score needs to stay relatively the same from application to closing.
