Since Airbnb remits at the state level when I see high numbers (or low) of what I am remitting for other OTAs/direct I then drill down to make sure listings are optimized on all channels.

Gradually scale by researching high-growth markets, partnering with experienced investors, and exploring financing options like SBA loans.

I was going to buy a owner occupied duplex with 3.5% down then buy an investment property using 25% down but my DTI ratio would not qualify for both mortgages in the same year unless I used a dscr loan but then the interest rate would be very high, and it'd be hard to make a deal work using a dscr loan because of that.

I see two high end homes for rent, 50k, 70k, 210k per month..

I would highly recommend you create an LP agreement.

I would highly recommend sticking to the 30 year option or not doing it at all. 

From a personal standpoint I target 70% LTV for any investment I have that way gives me ability to sell it if I need tooI'm Canadian so it a T4 up here and yes I'm I high earner who can handle vacancies if need be. 

Cleveland, Baltimore, Toledo, Indy etc....You will see net population decreases in most of these areas but these are the areas where the prices are the lowest in the USA and come with rents that are very high when compared to the sales price.

This is a straightforward process that we’ve followed to consistently deliver high-performance properties, and it does not require secrets or gurus.

It takes more effort and there's more risk involved (therefor more reward), but it just depends on your goals and how you want to get there.As far as focusing on areas with high demand for travel nurses, that's just 1 tenant-type of many in a changing landscape.
