I suggest you run your own numbers on them to compare.

Many lenders give better rates if the appraisers opinion of rents is 1.25%, 1.1% or 1% compared to the mortgage payment. 

A neighboring property, similar to my current rental property, is now on the market at the same price I paid two years ago, with comparable rent.

During the recent period of low interest rates I acquired some rentals with a 15% down payment in order to stretch my cash further toward down payments on additional properties.This helped with the down payments and my math showed that even with a little higher interest rate compared with 20% down and the PMI until I was able to remove that this would still be the wiser choice. 

Cah out can be used as an asset and for PITI reserves and a Heloc can "Never" be used as an asset or PITI reserves.I generally work out the options for my clients to compare a cashout to a Heloc so you can see payment to payment, overall costs and rate.

Options may include traditional mortgages, private lenders, partnerships, or even self-directed IRAs.Calculate all potential costs including property acquisition, renovations, property management fees, taxes, and maintenance.Property Selection and Due Diligence:Use your local team to scout properties that match your investment criteria.Conduct thorough due diligence including property inspections, financial analysis, and reviewing rent comparables (rental rates in the area).Make Offers and Negotiate:Submit offers based on your research and due diligence.Negotiate terms that are favorable to your investment goals, taking into account potential repairs or improvements needed.Close the Deal:Once your offer is accepted, work with your local team to complete all necessary paperwork and close the transaction.Ensure all legal aspects are handled properly, including title searches and property inspections.Manage Property Remotely:Hire a reputable property management company to handle day-to-day operations such as tenant screenings, rent collection, maintenance, and emergency repairs.Establish clear communication channels and expectations with your property manager.Monitor and Adjust:Regularly review your investment performance and financial metrics (cash flow, occupancy rates, expenses).Stay informed about market trends and adjust your strategy as needed to optimize returns or mitigate risks.Long-Term Strategy and Growth:Evaluate opportunities for portfolio expansion or diversification in the same or different markets.Continuously educate yourself on real estate investing best practices and market dynamics to make informed decisions.By following these steps diligently and leveraging local expertise, you can effectively navigate the complexities of out-of-state real estate investing and build a successful portfolio over time. 

I like to use a flat amount compared to a percentage since rents can vary depending where the property is located.

Therefore you should not need to change service panels, since since mini's are such low current devices(comparatively).

I often compare imputed interest to due-on-sale.

People in these areas do not have as much investable income, if any, compared to those who work in more affluent W2 positions.
