Financing is important but your realtor will absolutely be the determining factor whether you purchase correctly or not. 

Have multiple exit strategies, do not be over leveraged, and make sure you are factoring market changes.

Whether these factors outweigh the challenges is a personal decision. 

Not sure your situation financially but even your $100,000 HELOC is going to probably run you $12,000 additional each year in expense that you've got to factor in.

The cash on cash number is what I liked about it and I think the Capex will not be a big factor because of the Tenants already are there and have been there and want to stay for long term so vacancy was set lower.

Is it fairly priced for the size, location, quality, and other factors?

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

This will help you understand the qualifying requirements, key factors to consider when purchasing, and how to assess whether a property might be a good investment at first glance.

Factoring market conditions at the time of refinance, I negotiated a lower rate and conceded a lower term anticipating rates to normalize in the 4%-5% range by 2026.

This reminds me of how Alex Hormozie describes "the value equation"; Experience in this case is the factor that determines the likelihood of achievement. 1,000%Alex Hormozie is one of the greatest marketers not just alive, but ever.
