Lawn care typically $30-$50 a cut and snow removal I like to see if one of the tenants can handle that during the winter for a little bit off their rent.

How does one go about setting up a lien, and does the investor give us the money directly or does he cut a check to the bank for the Property?

I'm a big fan of seller financing because it cuts out the big banks and there's a story behind every note.Happy to answer other questions you might have.

You can have DAWGS put steel covers on your doors and accessible windows if necessary. 

The biggest time saver is a cutting tool.

I cut back my contribution to my Roth 401k to 6%, which is the max for the company match. 

Not to mention he steels all my pictures and plagiarizes my website and puts it on his clients website.

When I asked for pictures of what was done, they would not provide any, I had to pay an additional $250 to build a from step handrail, $200 to install a new bathroom mirror and light (the other what half way in the shower, they never fixed an interior window that they could not get anyone come and fix because of Covid, I got it fixed in 2 days) $300 to a cleaning service to clean up the house, $1000 for a dividing fence, $500 to a lawn company to come cut the vines and over growth on the driveway.

That is not clear cut. 

Unless you specifically work it out with your tenant to take care of the yard, in exchange for $$ or a small cut taken off the rent, you should expect to be responsible for that.
