My name is Luis, I am very responsible person and respectful.

For example, I think it would be nice to have a 20 year spreadsheet for LTR showing 2 roof purchases at the 10 and 20 year mark (assuming 10 year roof) and then each system listed with its expected respective replacement year to get a picture of potential capex spikes,This may lend to moving replacements expeditures around to balance the outlay of capex dollars over the life of the property.Thoughts?

Unfortunately STR mixed with homeowners and families don't work well together, even in rural areas.Outside of the destination type spots for AirBNBs, I do have a few that are in very, very good areas of their respective cities.

I've come to respect Seventy's and Woodruff's opinions. 

Is it an HOA item, or does each owner own their respective roof.  

Respectfully I disagree about the house manual not being important or guests not reading it anymore.

Our largest concern is respecting the neighbors and our most recent request came from someone that said he is coming in to town with two of his buddies for a college softball game.

The length of time specified in their rental agreement is 30 days and 10 days respectively.

At that's the approach I took with respect to my home country of Canada when I started to invest internationally.

Absolutely, but if you don't use subcontractors or have any w2 employees it adds overhead.Much respect to B-1's still operating in CA!
