We bought around 20 plus houses in a little over two years time.

This is very useful.You could build a deck or gazebo to house a hot tub.

Quote from @Antoine Black: I have a house that free and clear and I'm trying to tap in the equity can any one help  Hey Antoine, As Mike stated, your best bet is a local credit union.

Context, i bought a house at a foreclosure auction.

congrats on the first duplex. easiest will be house hack your next property. you can go higher in units up to 4 but just need to occupy the property. lets connect if you need guidance, i house hacked a few times

How many micro units will you have in that one house?

This is partially because we lose the OTA protections and partially to make sure we follow the same procedures for all residents (fair housing laws are important to follow). 

You can usually request this from a title company or look into public records in your county’s clerk or recorder’s office.If you’re not sure how to navigate this, contacting the auction house or a real estate attorney familiar with foreclosure auctions can help ensure there aren’t surprises.

So house for house, apartment building for apartment building.Have your parents considered renting the house they are living in for two years and moving back into the rental unit for 25 months.

There's lots of opportunities in developing neighborhoods, but also seems a bit saturated at the moment.Also, definitely budget security (remote control cameras, alarm system, etc.) for your properties, as there are a lot of people who occupy themselves by breaking into houses and stealing anything they can sell.Lastly, there are a ton of contractors looking for a quick buck.
