Maybe  DSCR 2nd if both the 1st and 2nd mortgages meet the debt service requirements. 

Currently, the property is rented at $2100/month.The house, built in the 1900s, requires significant renovation, and the tenant frequently requests various repairs and maintenance, such as duct cleaning and appliance upgrades.

@Douglas SkipworthLike others I am required to track it as well.

These could lead to leaks or blockages, requiring costly repairs or replacements down the line.

Does that mean net cash in your pocket after interest, taxes, principal, insurance, repairs, maintenance, credit card fees, etc.?

In my experience, Banks make it really difficult to obtain a mortgage and I have never been able to succeed in obtaining a loan with them for investment purposes simply because they require a certain amount of DTI ratios.

There are specific requirements though when using the rental income.

Can I count these hours towards the hours required for REPS?

NACA takes out a lien on the home to ensure this requirement.

They do require a refundable $5k deposit to get on the "VIP" list and start receiving properties.
