You are entering a dangerous area. 

When you analyze a market properly (1% Rules aren't properly), you're analyzing all the properties in that market at the same time.It's even more dangerous for newbies to use any Rule of thumb.Rules of thumb are nothing but shortcuts, which seems to be the growing method of doing anything now. 

Also, as I love REI I try to focus on that as well and would love to work with some investors in order to share knowledge and learn from each other.Also, I try to provide free content to my followers on my social networks about real estate, but it's everything in Portuguese though... shame :/ Feel free to ask whatever, if I can help, I will.

@Spencer DixonRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

Very dangerous action.

So how do I socialize the benefit of doing something like taking a 200k ADU construction loan to add $X in top line and $Y after servicing the new note, but with an increased property value etc etc? 

If you're curious - read it here: https://www.biggerpockets.com/forums/51/topics/1221700-rant-...In closing: The dangers of shifting the timing (of your income, expenses, and business transactions.)A purely mathematical exercise may indicate some beneficial timing for this or that.

I also look at it from the perspective of I now have extra cashflow to remove dangerous trees or do preventative maintenance to systems that have higher likely hood of causing damage.For the management I self manage for now so that fee just goes to me.

The other California investors with more moderate incomes bought years ago and have built wealth from 30+ years of appreciation and small mortgages and their rental income supplements their pension or Social Security and retirement accounts. 

If he sees a guardrail loose or dangerous electrical installation, call it out.
