My suggestion is be totally upfront with the landlord so they know what is going on and they can take the proper measures to assure they are protected, you are protected and you cover all insurance and wear and tear costs. 

Let's clean up the "way" you think about this a little bit, so you can zero in on your target more quickly, with (less) wasted effort.Instead of measuring by time (who knows if it's enough, or way too much) measure by Bullit Points on your phone.Make a Bullit point list (or if it feels to big use numbers vs bullit points).In reality there are four things you can do:-- Buy and Flip (when the times are good for flipping) (20% down)-- Buy, Fix and Flip (when the times are good for this) (maybe 100% cash???)

In order for lights on the outside to work as a security measure, they would need to cover the exterior of the property...and be bright enough to be effective. 

Yes, I know that's lots of homework but this is a measure twice cut once type juncture in our market where the high-interest rates and high cost of entry at this point make it more valuable for you to understand what you're looking for and buy correctly.Once you get a sense of this style of investing you're trying to pursue strategy wise there's lots of content available especially on YouTube, here on bigger pockets, and in podcasts.

Still move ahead with some of the sound-proofing measures discussed above. 

@Michael Shabazz CHCCA is not necessarily involved in the process, though Urban Design Commission is very stringent.

This property measures around 1,006 sq. ft. but the title shows only 660 sq. ft.

Whelton’s studies, chemicals were still leaching from some PEX pipes after 30 days leading to measurements above EPAs odor threshold and with similar findings in field studies from samples from homes where pipes were 1 and 2 years old.

On the bottom of the meter there are usually bolts and a gasket that are used to access the measuring cup/nutating disc in the meter body.

Chris did an awesome job of answering this, it's really a matter of how you're measuring ROI.
