Our housing prices are insanely high to begin with.We take adjustable rate mortgages at levels you would never see in the US.

But start to get out of the SAD (sad american investment diet).Real Estate Investments: Cash flow and appreciation aside for you as a high income earner over 400K AGI its going to be more about saving taxes.

High real estate taxes and older homes requiring a lot of repair and maintenance. 

OUCH I thought $2800 on $600k wa too high.

It honestly is the only way we can still acquire property in this high interest rate environment.

I also learned of landlords (at least in one case) that are getting HARMED by high volumes of text spams and calls from investors.  

Start a little high as you can always lower your asking rent if no inquiries.Be sure to have a solid screening process & lease!

Just want to negotiate a best case scenario resolution.

Long term my goal is to quit my high paying job (great pay but long, erratic hours and stressful) by achieving 6k/month passive income. 

That said there are other more expensive products like MH Ready Patch (original formula with high VOC levels if you can find it), Synko Patch and DAP Platinum Patch which are designed for both interior and exterior use on wood, plaster, masonry, etc.
