I then show them another unit on the same property to needs to be completely renovated (cosmetic and hvac serviced etc).

You are correct re: last 5 to 10 years but all locations have cycles and helpful to understand where in the cycle you are and just understand that if you believe you are in the later innings based on historical averages of the complete cycle does it make sense to jump in or not or find better markets in different parts of the cycle.  

The off white may be a very light member of the greige camp, but the other two I would call bone and...well, beige and not greige and not tan and not almond (note, I am color challenged but beige can be yellow or pink and while neutral, completely outdated due to undertone...my first and last quart of greige, used as asubtle accent wall, had a disappointing purple undertone.)  

I have a rental property in Newark, Delaware in need of some window repair (maybe a complete window replacement).

If you are maintaining a business entity for your rental properties, then you do want complete separation between your personal and rental business.  

This guy claims for $1,400 that he would help you find them and apply.

However, since both units are rented this would be classified as an investment property in which case your rate will probably be 4.00% to 4.250% on a 30yr fixed depending on FICO credit score.The maximum loan to value for a cash-out transaction (investment property, duplex) is 70%.Based on the information you've provided it doesn't appear the value is high enough for the property to be eligible for a cash-out transaction but you can still remove PMI.If you want to send me a PM I can run a complete analysis to see if removing the PMI will offset the slightly higher interest rate.I'm also licensed in CA so if you're looking to purchase a property I can help with that transaction as well.

It's completely normal for a title company about to issue a title insurance policy to discover something during their due diligence, that you didn't see when you pulled a title report for the exact same property from the exact same title company.
