Wayne Brooks I agree that this landlord made a bad choice in choosing tenants.

If you get a reputation for over-priced properties, low rehabs, and/or inflated ARVs, your properties will sit.

Whatever way you choose, I'd suggest just make sure you can repeat it later.  

If your goal is to be an active real estate investor and call all of the shots, option 4 is your best fit.If you want to be semi-active and call some of the shots, option 3 may be a good fit.If you are looking to add real estate to your investment portfolio but don't want to be active (similar to the stock you own in companies managed by others or mutual funds that manage portfolios of stocks) then option 1 or 2 may be a good fit if you align yourself with a good sponsor.If you choose options 1 or 2, whether you choose to do that with Praxis or any other sponsor, the most important component is to thoroughly research the company.  

So what I've sometimes done is pick and choose from their estimate what I want them to do, and what I want someone else to do because I think I can get a better price or better quality of work or both.

How do I go about choosing the right city and what data sources do I take advantage of in making this decisions?

As such, I've worked with these portals quite often over the past two years.What I've noticed is that the original goal seemed to be to get investors equity positions in large scale real estate projects - commercial high rises or 100+ unit apartment complexes.While this has worked well for a few very large portals mentioned earlier here, the reality of the situation seems to be that many of the fledgling portals did not work out, grow to sufficient size, or build enough of a reputation quickly enough. 

My suggestion would be that you speak with an experienced mortgage broker,  describe your situation,  and let them help you choose the best financing for you.
