I lost contact with the lady living there but her boyfriend, that I have only met once (he is on the lease but never lived in the house) tells me her ex-boyfriend was creating problems so she moved out and is not able to talk...

You typically buy real estate, hold it a long time, and patiently watch it grow into something incredible. 

However there are always things to watch out for: Builders cannot build quick enough now (demand is too high), so a lot of them cut corners; if you have a highly skilled agent they can go to bat for you/keep an eye on the builder as you are out of state.

We are planning to manage it ourselves.We would live close by.I am currently reading and watching everything I can about landlording. 

A video of no more than 5 minutes, but preferable 3 minutes or less, will be watched.

I also watched Peter Linnenman yesterday on the Walker & Dunlop podcast and he predicts 3 rate cuts the end of this year as lagging rental data in CPI starts to hit, and he also thinks a recession is several years off.

If you're not yet aware of this niche strategy whereby you can leverage your real estate assets (single family, multifamily, hotels, etc.) to generate significant long term cashflow, this is the podcast to watch. 

@Colin Emerson - I have not pursued his education but have done some throught the tax lien lady.

I had been watching this property listed overpriced for many years.
