If you don't understand the basic principles of construction, market standards (i.e. average cost per labor hour, cost per sqft for flooring, cost per sqft for hang/finish drywall) then you may find yourself getting taken advantage of without even knowing it.

LOL I didn't even realize that!

Even better if they are small multis. 

You could see an attorney or even better talk about it with your financial planner many have legal tech now that makes it essentially frictionless to get your estate work done and keep it updated.  

That is the skinniest deal I will even consider.

Figure out how many sales you need to break even.

Your old carpet did not become more valuable over the seven years you owned the property, even if you are selling for a gain.

The loan is with you, not with your tenant, so none of that means anything to them - in fact because you live in one unit and it's under 4, if you were self-managing you don't even have to abide by fair housing laws (at least on the federal level). 

Even with 10% down you’re “hoping” that’s all you lose if it all goes wrong. 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.
