I love this option, because you can leverage low down payment, get benefits of real estate, learn a lot of valuable RE skills, and can maximize your income with a furnished rental.As a SFH, you could potentially rent out rooms or an additional space out as MTR/STR, but there is potentially less privacy.

Now, my time is more valuable than saving money on the renovations, so, I sub out every part of the rehab.

Network with other individuals there and I'm sure you'll gain valuable information from them.

You point out a great deal of valuable information. 

Additionally, networking with experienced investors and seeking guidance from professionals can provide valuable insights tailored to your specific situation.

Do you think the lot is more valuable sold as a 51 acres or divided into 3 17 acre lots?

Full guts of the bathrooms, replacing all fixtures, throwing modern tile finishes for the tub/shower, new vanity, new cabinets in the kitchen, island, new stainless-steel appliances, new flooring throughout, new recess lighting, and likely new siding on the property to give it a more freshened pop for when it goes back on the market.

These forums have become decreasingly valuable when the only responses are relators telling me it's only for their use.

Once they realized what happened they lawyered up  this was a extremely valuable property  we paid almost 200k for it in the early 80s which was a monster sum in those days for a tax sale.. the chances of this happening again are remote and like I said very few improved properties ever sell .. so unless your talking about putting a well and or septic on a property I would not worry about improving them.. or having the sale over turned etc. its the title companies that just dont want to take the risk on these for any any reason..

If you are able to make considerable improvements in those first few years while living there, being an owner occupant during that time also allows you to take out a HELOC on the property much more easily than on something that's already a rental, giving you valuable access to capital for subsequent projects.
