Speed of building a portfolio (Cash-on-Cash return is a factor here)?

My wife and I are looking into building a duplex on it.since I am still learning on investing in real estate.

Improvements that DON’T drive the ARV as much: Windows, Landscaping, Driveway, Rough Plumbing & ElectricalI agree with @Jaron Walling about meeting the appraiser at the property and providing documentation.

I had to have an awkward conversation with my favorite realtor when their broker suggested everyone had to pay a $700 “document fee” on every sale.

I asked specifically about transfer in PA from personal ownership to LLC...so maybe it not considered a "sale".Thanks for the input on the personal loan vs LLC, this is what I was unsure of as my name would be tagged to the property via the conventional loan document. 

However, if you're a W2 high income earner or business owner, I can't imagine it makes any sense to flip houses, mail mass post cards, wholesale, or build lead gen websites with the value of your time being better spent other places (such as learning about real estate and increasing your income through proven means), such as at your 9-5pm or growing your business, and your real estate is a long term process and you don't need "home run" deals to qualify or make it work.

But my realtor said they are going to do special assessment on this property and HOA runs badly. ( We requested HOA reserve document but no answers. ) We wanted to wait to see how special assessment going and close. 

. - So, recommend having that first hire document the crap out of what you want them to do.

I got into this by accident when i took a job via upwork as a VA  for Vontive and stated at interview  i could lower there costs and stress by automating there lead gen.I automated the lead gen and they didnt need 5 0f the 6 VAs they hired and we cut there costs by nearly 60%.Thats when i realised that you could automate even the cross platform data scraping.Then i got some extra clients from Upwork and now Im on here to help, offer the same and expand to others.going to the recorder office/courtYou only need to go to the physical building if thre is information on the documents that you need but cant view online.

You could build or flip less expensive units and sell them to your clients/occupants over time.
