I'm not sure that a block deal for 9 homes is such a great deal when, even if Zillow is slightly low at average of $165,000 per (and it may be high), it sounds like you're basically a roof and a heat system replacement away per unit from full retail, and then you're saying the owner basically wants as-is but gets near top dollar for each one. 

Looking for an advice on the most effective and efficient way to block up an old basement window.

I am in the power position as MY Properties are the best kept on the block, the rents more than fair and the rental demand is HIGH!  

We knew the area the property was located in & it was located just 2 blocks away from the local elementary.

It’s unfortunate and funny how just a couple blocks over it’s not nearly as bad. 

I can add value by recommending great contractors in concrete (driveway and sidewalk), painting, tile, and roofing—if someone is not mentioned I'm sure I can find someone.I look forward to connecting!

If you are looking in the city, things can change block-by-block. 

The HOA reached back to us and declined mentioning a rental cap on the community of 20% that currently is at 24% blocking us the option to rent.

Concrete evidence that what I am telling you is the way to go!
