For the PM biz we use Veryfi and for my personal properties I use AMEX's Amex Business App which allows pic uploads and transaction tagging.

It depends on the lender but at a min they must follow TX SML or lending laws in the state in order to compliantly lend in TX, on whether choose to apply this guideline to all types of occupancies or transaction types (non owner investment, second homes/primary residences, etc)80-85LTV on rental properties is only on the purchase for fannie/freddie loans but on rate term refinances its max 80% and cash out max 75% for 1 unit and up to 70% for 2-4 unit cash out conventional.On HELOC's and rentals are up to 70-75% depending on the HELOC investor or product.Its good to distinguish between what the lenders are willing to do and for which product and also these loan products must abide my state law as well as an additiona layer of "overlays," on top as well (whichever is worst / most conservative).

You will need a RE attorney to transact this sale.

To clarify my assumption about current equity: most transactional activity in the area has been new construction and established neighborhoods of "better" quality.

The transaction allows investors to increase the liquidity and diversification of their real estate investments while deferring costly capital gains and depreciation recapture taxes that may result from the sale of a property.Benefits: REITs also can provide the same ongoing benefits of real estate ownership including income, depreciation tax shelter, principal pay down, and appreciation.

Are you doing your own sets of books?

As @Allen Duan said 1-2 bedroom are the sweet spot for traveling nurses, but that being said we have a 4/2 that's stayed booked consistently.

Not a course, but I recommend the book "Crushing it in Apartments and Commercial Real Estate" by Brian H Murray.

Does anyone have any good recommendations on books or accounts I can follow or read to learn more? 

Quote from @Sarah Albert: As discussed in my book, it's best to address these situations before they happen, because they will happen.My lease has an early termination clause that explains the process and penalty.
