As @Michael Le said the returns projected are for investors so the numbers need to reflect the returns they will see on their investment.

Thanks for sharing, this story has really inspired me because I also live outside of my home country and often reflect on the difficulties of trying to be a REI from afar.

I guess that's partly because I don't feel I have a whole lot to offer, but having reflected on that idea a little bit, I decided I'd start contributing in whichever small ways I can in an effort to give back something to this online community to whom I owe so much. 

If they reflect on your tax returns lenders do have ways to use the rental income to offset it.However you are correct when it comes to a DSCR loan making qualifying easier and it would be a business loan.1) Typically you would want to expect rates about 1% higher than a conventional invsestment properties ranging from the mid 8s to mid 9s right now depending on the specifics of the loan.

The increase in rates is likely to be reflected in mortgage rates. 

Find the more guaranteed and niche with the least resistance, then pursue it.That is the answer and anything else is a reflection of someone else's life pursuits.

None of the pro forma statements reflected much profit if any. 

Since the market has gone up drastically in the last few years, your new tax rate will reflect that.  

This was not noted in MLS due to some issues with the lender, and the buyer needing it to be reflected as one home

OP disappeared but a good place to start would be a BP Pro or Premium membership where you get access to lease agreements and related forms, disclosures tailored to each individual state.Go here: https://www.biggerpockets.com/perks/pro I believe BP hired local landlord/tenant attorneys to prepare these packages... and I assume they would be updated periodically to reflect any changes to local law.
