That tool really sounds ideal...I think in most major markets now that are either saturated or balanced in terms of supply/demand now more than ever amenity rich properties are a must. 

There is so much inventory that owners are turning to annual rentals and now that market is completely saturated.

This implies that cash flow growth historically is non existent in inflation adjusted terms. so the $122/unit cash flow is unlikely to increase in inflation adjusted value   It appears that numerous expenses are missing, the property historically has depreciated in inflation adjusted dollars, and even with the expenses you provided, it cash flows $122/unit    To me this does not justify the effort of owning residential units.  

Those tax breaks existing in the first place are examples of politicians intervening to artificially change market dynamics, by stimulating investors to buy those properties more aggressively than they would in a free market. 

And you can avoid the large transactional costs of having to sell your existing properties.Since you can cashout refi up to ~80% LTV, you're not going to get that much more capital to upscale by selling and doing a 1031. 

A saturated and expensive market. 

Competent sponsor, capital call large enough to completely escape existing toxic loan with cash-in refinance to a lower-balance loan with a long maturity—good outcome possible, even probable, if there is no other “hot money” in the deal such as preferred equity or priority share classes.There are surely other nuances I’ve missed here, but this is a start. 

The two primary banks I worked with no longer exist  and all of my original banking relationships have moved onto different banks/lending institutions.

Outside of my insights from data, there are a few things I'd like to pop in here to hopefully take this conversation in a direction that helps us all learn from this and grow in our businesses together, elevate the industry together, find a path to co-exist where each business contributes to the overall industry growth... challenges the other to innovate and create fresh new solutions for customers to win big... and leads towards our industry getting stronger not weaker. 

I painted it, redid the floors, put on new doors and hardware, fixed all the existing issues (leaks in roof, toilets not working, sinks leaking, water damage on exterior and upgraded the panel to a 220V) What was the outcome?
