or can I only have 3 mortgages outstanding in total ? 

Like others have mentioned, you will pay structurally more for a home warranty than self-insuring for the cost of repairs.This may be worth it if the value proposition was that you could be hands-off whenever a covered item breaks.In reality, it adds significant overhead because there is the claims process and you give up control of the repair timeline and quality as you have discovered.

Obviously paying interest on underutilized capital is sub-optimal but when factoring in the cumulative proposed transactional savings, the annual total interest cost could be equivalent or lower than the net of an alternative home equity line of credit on the same principal loan amount.One 'hack' could be to delay the actual closing of the DSCR loan until a quality purchase prospect is identified and/or near under contract.

Having boots on the ground with an STR can make or break the guest experience, as well as preventative maintenance and quality upkeep of your unit. 

We were not getting a ton of leads and I quickly realized the PM just posts on Zillow and waits so I started hustling on FB market place and commenting on other people's post in the local Facebook groups.Lot of junk applications but did start to grab quality tenants.

The current market value of the NC property is around $260k, with an outstanding mortgage of about $160k, resulting in approximately $100k in equity.My current residence in Beaufort, SC is a 4-bed, 3-bath house with a higher interest rate of 6.5%.

I fixed them up, raised the rent to market, and placed a higher-quality renter.

Are their listings detailed with good-quality photos?

But anytime ANYONE says "they are the best" or" have the best quality"...Run run away.

Mid-tier quality, mid-tier finishes, mid-tier service both pre and post closing.
