I would think the biggest red flag would be asking for any fees other than an appraisal up front - would you agree?

Many investors use a general rule of thumb for midterm rentals that they should earn about 50% more in rents than an equivalent long-term rental (whereas short-term rentals should earn double or 100% more than if the property was utilized as a long-term rental).However, for DSCR lenders, change can be slow and challenging, and many lenders prefer and require more precise qualification measures than rules of thumb.

This seems like a better option than an FHA at ~6.1%.

Visio specializes primarily in DSCR loans for short term rental properties (think airbnb or vacation rental rather than an annual lease tenant).

To clear up things though if you have an LLC just for rental properties you won't get any tax benefits for having an LLC other than an additional expense.

Even if it can do this, 90% of homes will sell for more to an owner occupant than an investor, maybe 99%. 

Anything less than an "A-" rating should probably be avoided.

It's a wish rather than an informed goal.I find it better to focus on systems/actions (analyze X properties, offer on Y, close on Z).

You have a better handle on reality than an investor who allocated 15% of $800 rent to cover vacancy and maintenance/capex.  

In the Reno, NV market the midterm doesn't bring in much more income than an LTR unless you're in a more tourist area but then you're paying more for the initial costs.
