I'd add up all of your costs including vacancy, repairs, maintenance, insurance, HOA fees (if applicable), etc before deciding.

My current issue though is that my mortgage and insurance have gone up to where it no longer seems like it would be valuable as a rental.

I can't help with that.Regarding insurance, you will need a STR policy.

The lower of the current rents and market rents are used to determine DSCR, but some lenders will go up to something like 120% of market. 3.DSCR is calculated with principal, interest, taxes, insurance and HOA (if applicable) vs rents.

Another big one would be $3367 in Lender's Title insurance.

I've been in the insurance claims business for 20 years and not everyone gets that a modern mobile home tends to weather a hurricane better than most framed homes.

I believe there are specific bookings where you can get 3x LTR rates, for example insurance bookings.

We are stable long-term tenants and would prove to be a good investment choice.

I have a lender, I would work with the same law office as previously, I have an insurance agent, I would find a home inspector, I would coordinate with the lender on the assessment - I feel quite capable of managing all of that. 

Generally speaking, however, LTRs command more stable cash flows over time than MTRs or extended stay arrangements, and may be the better (and lower-maintenance) choice for someone just starting out.
