I was wondering if anyone had ideas on how I might be able to attract more tenants who are okay with having this type of policy as I know it might be a bit of a niche market, but I'd love to hear any suggestions.

I highly suggest using IDI data.

Any landlords have suggestions ?

I might suggest getting your own appraisal where you select the appraiser that knows your situation and you can talk to and discuss their approach.

No lender will lend on a deal that doesn’t make sense.4) After the appraisal comes back you will get a document that outlines the amount to be borrowed and all fees that will be relating to the loan (I would suggest to ask for an example of this document when you are searching for an HML so you will know what fees are going to show up).5) Close the loan at a title company of your choice.6) Begin work and make draws on any repair balance.

If it's a good rental and you don't need to sell, sit tight but if you can sell at a profit and reinvest into a better property I would suggest that. 

I've done a lot of research and even worked on running numbers for certain options (just as an exercise), but I'm now looking forward to jumping in.

I was going to suggest wood if unable to afford vinyl.

Here are a few suggestions on how you can maximize the wealth of information available: Check out the blogs and podcasts, or take advantage of the search feature (magnifying glass).

I would suggest look for a property management company to manage the property for you and slowly increase the rent yearly before selling.
