But if the additional mortgage payments come from a different  loan (Heloc) with similar interest rate as the mortgage, there is no financial benefit, which has been shown repeatedly in this discussion.

I’ve been working with several lenders for DSCR loans, but I’ve found that the fees are quite high, with minimal benefit in terms of lowering my current interest rate.

Just one additional option.  

I've also leveraged their webhooks to automate additional things on my end like setting the thermostat to the appropriate temperature an hour before the guest check-in and turning it off after they check out.

You may be able to see if a retailer still sells the 2024 version.If you can't get the one time purchase, you would need to see if the cost is beneficial.For real estate -  Quickbooks desktop > Quickbooks online because you can set up multiple entities within quickbooks desktop and not pay an additional cost per entity that Quickbooks online would charge you.Best of luck! 

In addition, the gas bills have shut off notices and are not being paid. (3 units are occupied and utilities are all paid by owner).

Quote from @Tim Buckingham: @Jonathan Moody Good information but I'd like to add some additional points (note that your mileage will vary due to numerous variables). 

Additionally, I have $100,000 in cash in the bank, and my monthly expenses for my home and family are around $3,500.My wife earns between $100,000 and $120,000 from her W2 job, while I've recently lost my job but found a new one that pays $65,000 a year.

In addition, due to the 2 of 5 year rule there often is no need.  2) you cannot 1031 a property that has not been put into service to be an investment property 3) you cannot 1031 a flip.  

Additionally, the price point is still cheap enough to find the 1% rule and positive cash flow and there's amazing appreciation potential.
