First you have to determine if you want to go Lead Free or Lead Safe.

The most cost effective and safe investment you can make to cover your 50K debt and still use the same 20K capital to increase the value of your holdings is invest in short term fx government treasury swaps.

If you feel the need for non-recourse, could it be the deals you are doing are not as safe as they should be?

If there are items you need to replace and they are less than $2,500, you can take advantage of the de minimis safe harbor election, which allows you to deduct those costs in the current year rather than capitalizing them.

People have cars, they work from home, they don't want to look for parking, and they want to feel safe.

You might want to research syndications to invest safely (vet the sponsor) and learn a little.

Then I would just be taking the easy/safe way. 

Is NACA a safe loan program as well because it seems a bit too good to be true. 

However, I always caution that, if you are using the LLC as cover for being negligent in providing safe accommodations, it will not protect you.

What condition is the house in, what is the rent, how many bedrooms and bathrooms, how is the school system, how safe is the neighborhood, etc.
