Thank you, super helpful! 

In my experience like other things you get what you pay for. if you go with the companies that are charging super cheap rates - 5%, $100/month or something like that they don't have enough income to sustain a supportive team to actually help you manage your home. 10% is the going rate it seems in the city and that is where the better companies tend to exist. 

They (HOA manager, HOA president, and HOA attorney) inform me that there's a super lien on the property and that I have to pay it.Of course I pulled an O&E before purchase and there was only the mortgage lien (foreclosing lien) on the property. 

Quote from @Jay Hinrichs: my advice is to get some cash first.. dont be so focused on super high leverage. do seller finance first .. forget sub too until you are very well established and have ability to cash out the loans or refi on a moments notice @Don Konipol  Don gave you chapter a verse about the sub to risk/rewards.

Chatgbt is been super useful in helping with resources like this.

I'm super happy with BP as a great resource for more traditional real estate, but I'd like to do some exploration into land hacking as well.

That is super exciting!

The forums have some information, but the bigger value is in their various member meetups, since it seems the forums are not "super" active with sponsor conversations.  

Also most of my units are super nice so rent is already at a higher premium than some of the competition charges.

The super came and said it is because of the wrong paint used not the vent.
