Address the mailer to the owner by name. 

The tenants are month to month right now, so I would have to get them out to do anything significant to address anything major.

I come home with about 12-20 addresses which only lead to about 3-8 leads that I mail too.

Ask them the addresses and then look up and see if they ever owned the property. 

You can find out information like who owns the property, their mailing address, plats of the property, what the tax assessment is, number of beds and baths, square footage, acreage, zoning... etc.

Hi Alex, my advice for you would be to prepare a solid investor packet for them, regardless of relations: friends/family or Hard Money lenders, show them how you will put their money to work for them, the investment strategy and how it works, allay their fears by addressing risk, how you are protecting them and what your risk mitigation strategy is, Breakdown the deal for them and Address the benefits of why it is they should invest in you and your system versus keep their money elsewhere.

I would say they should limit accounts to 1 per phone number or ip address but I suppose professional trolls would get past that. 

PM me when you are ready I do not know Axel's methodology to have any opinion but I will address how I would do a House Hacking BRRRR. 

He is very dedicated to his nonprofit and has been vesting the property over the last 8 years, wanting his nonprofit (addressing global health issues) to have long term funding and his legacy to live and getting a tax write off.

Those taxes next year will pass almost 30kThe house has really solid bones and a few upgrades have been addressed already like the roof and some plumbing issues.
