@Tereza Dyerova I run into this issue all the time in Chicago due to the high quality of a lot of the construction of the homes and the high cost to re-build them if they were to be a total loss.

Any difference quality or cost?

Their quality of life must be suffering and the eviction notice might be the impetus to get their family to take the situation seriously and help them.

And are you going to attract lower quality tenants telling them you intend to sell the property while they are renting.

I both sell and purchase properties via the lease option method and one of my protections as the lease option buyer is knowing that the seller / owner cannot sell or refinance the house out from under me as long as I have that recorded option against the property effectively creating a lien. 

It's the quality of the asset.

I would recommend finding a good, quality, honest and ethical lender and sticking with them.

Ultimately, our goal is to utilize the BRRRR  method but that would be years down the road when we can bring more cash to the table. 

What training course do you suggest to learn this method?

I've known multiple people in this area that do BRRRR method but they've always had an in (real estate attorney, contractor, realtor, etc.) in order to hear about the good deals.
