But now that I have developed the Developer “eye” there are great investments everywhere.  

I'll keep my eye out also

A HML's money is cash in their eyes. 

There's a few more great networking meetings too, so keep an eye out for them to pop up once things settle down with COVID. 

However, I started reading the book Remtal Property Investing and it opened my eyes about alot of stuff.

I would need to constantly be able to keep an eye on it, and also be sure my employees are being honest.

I've got news for you... you're not keeping your eye on the ball.

If at any point the property owner pays off the overdue property taxes before the lien expires (period may vary by state), the county is the party that earns the interest.Properties that are owner-occupied (as indicated by a homestead exemption showing up on the annual tax bills) or have a mortgage are most likely to be bid on because they have a higher likelihood of being paid off either by the homeowner or the mortgagee (the lender); the homeowner probably doesn't want to lose his/her place of residence and the lender probably doesn't want to lose its investment.If no one has bid on a lien, there are likely issue(s) with the property that, in the eyes of bidders with investor mindsets, render the property valueless, for example:the property has no direct access (landlocked or waterlocked),the property is too small to be built on as-of-right per the municipality's zoning codes,the property is contaminated (a Phase I environmental report would scour records on the property to see if contamination is likely, and if so, a Phase II environmental report would be done and soil, etc. samples would be taken to confirm the contamination),the market fundamentals indicate little probability for profit given the level of risk, such as high vacancy rates, low rents, or slow sale/rental velocity,the property is in a "poor" location due to many of the types of things that turn off people looking for a home in which to live, such as high crime; poor or nonexistent infrastructure, such a streets, water & sewer, etc.; too rural/too urban; neighboring uses detrimental to the property's value, e.g. railroad, warehousing/industrial district, jail/prison, cemetery, etc.I hope that helps!

But since they are a step between doing everything yourself and having a full-service property management company handle everything for you you should expect to have some time invested in the venture even if you use a marketing and booking service.It is great that you live close by, that will allow you to keep a close eye on the property and quickly handle any maintenance issues yourself instead of having to hire a service to do it for you. 

Being only two units, that NOI increase doesn't necessarily increase value in an appraiser or Bank's eyes.
