Hes already put $500k of his own cash into it.

Can someone provide insight, a template and help with how to best send this notice?  

Recently, my property taxes and insurance costs have increased significantly, turning what was once positive cash flow into negative cash flow.

Happy to send it directly if someone wants to DM me.The guide is unattributed and has no promotional content other than on the last page there is a brief mention of the RI Coalition of Housing Providers (a landlord advocacy group which tried to work with the legislature to mitigate the challenge of this new law) and RI Real Estate Investors Group (a networking and education group that has educated RI landlords on new laws like this since 2003).Hopefully everyone reading this is already aware of this new law and has already submitted their info to the new registry!

While that is a good amount of information provided, you really would just have to ask what terms fit their needs best and go from there.

Currently, I don't have any second mortgages or helocs because the idea of keeping track of more than one mortgage per property has been a tad daunting and decreasing my cash flow at the moment is something I'm battling mentally with.

(The real money in real estate is in the long-term buy and hold anyway, not in the month-to-month cash flow.) 

They are providing the money for the down payment and have in fact already transferred $100K to an account in my husband's name. 

Something that throws off some cash flow and will continue to build equity (either through rental or price appreciation). 

I could also ask him to provide a report from his business (he is self employed) of his P&L and transaction reports to make sure he is making money etc.
