It sounds as if you're not happy with the asset, the size, the unit mix, and its performance.You could wait until rates drop, and find someone willing to pay a higher price than now.

Everyone recommends Quickbooks, yet it is not a one-size-fits-all solution esp. when its annual price can be $1000+.

You may have a grasp on this aspect, but there are items to consider that can play a big factor when choosing your land such as topography, existing zoning & platted lot status, minimum/maximum requirements such as parking, detention, size of building, setbacks.  

It will depend on the size of the house, the scope of work, and the quality of materials used.

Generally the fees are going to be very rough on DSCR Loans of that size (as a percentage of loan amount) but probably no choice right now - the market for DSCR Loans under $100k is very small and less than $75k even smaller. 

However I call one of them explained my situation, currently starting, getting to know the value and look for lenders, however his answer was not what i expected, he let me know they are looking for investors with money so they can help them...So I was wondering If you have any advise/opinion/comment on;Would the fist step  be get to know to what financing amount I have access to, based on my employment and credit score?

If I were in your position, I would either - Ask for the nurses contract or recruiter contact to verify employment and use this as the background and credit check (most travel assignments require you to get a background check prior to going to a hospital, and the contract would prove employment and term) - Offer the nurse a month to month rental with options to extend but require my cleaner to go in every month to clean and assess"

What is your experience / track record with this type and size of investment? 

We are sandwiched between well known hot spots and its an ideal location for someone who wants to explore the beach life or any of the down-town areas nearby (Los Angeles, Long Beach, Redondo, Manhattan, Southbay Etc), new build with modern amenities, washer/dryer in unit, full sized fridge, dishwasher, professional range cooktop, queen bedroom, full standing shower, large kitchen, full sized couch in the living room, private front patio. 

I have a size-able portfolio that is a mix of commercial and residential.
