The original post mentioned Passaic County - but rent control will vary per municipality. 

@Teddy MaoThere are many REI opportunities in different markets - markets in the Midwest and Southeast of the country are really great - where not only are the purchase prices reasonable for most RE investors, but the homes are turnkey (new builds or completely rehabbed homes, tenant ready, systems 10 years of life remaining on them, property management teams in place) with appreciating home value AND appreciating rent.

If you wish to buy rentals using your retirement funds you simply need a self-directed IRA (or Checkbook IRA if you wish to have more control). 

What's the condition of major systems like plumbing, electrical, and roofing?

Assuming you as the landlord are responsible for pest control, get the flea issue treated. 3.

While some property management companies may prefer to control the listing for operational convenience, it’s crucial that you, as the owner, retain ownership to safeguard your reviews, booking history, and overall control of the property.

One's name is Bob Diamond - America's Tax Sale Attorney and the other is Shawn Buige and his system is called Surplus funds riches. 

The support system I have set up is Connecticut based in the Hartford County area.

Taxes, insurance, pest control, utilities, software, etc comes out to around $13k per year each for my 2 bedroom cabins.Also unplanned capital expenses will add up.  

They need a lot of systems to be in place and need a LOT of attention on the marketing and maintenance sides.
