Unfortunately, there is really no best and quickest; it's all going to take time, a lot of reading and some understanding of basic repair.

My last property in 2 years I had to call a plumber twice, a heating/AC technician once, and my handyman 3 times.

I'm basically at the end of the rope with him and its time for him to pay the piper

I’m not an expert on real estate or multifamily but I understand the basics and can probably provide some help if it’s on a basic level of simply wanting to own rentals.

New paint, new windows, Central heat/AC.

You can have him sign the title over to you and basically take it sub2 that way you can control the property and resell.

I'm a little unclear on the actual process of having the interest in these notes assigned.I know it involves an basic assignment of note, having the named-insured on the insurance policy changed, and notifying the borrower of the change.

Basically paying for your place to live.Nothing is set in stone, do things how you feel they need to happen.

It is heated with a gas boiler.

I'd basically be cutting out a huge sector of the buying pool.
