The mortgage, taxes and insurance are combined in escrow.

I like buying them at 90-95% face value and combining that with other discounts

As others have mentioned, state and local laws, in combination with the terms of the existing lease, will determine the necessary notice period and whether there is a limit on your rent increase. 

I use a combination of Zillow, Redfin, and FindCompsNow and I find them to be missing a small peices of data some times.  

AllWe have a contract on our first home to start flipping, (exciting) from asking around we have received different answers to our question, "what insurance should we carry for flipping homes".We have received the following, Builders Risk, Liability, Home owners and few others, should we carry one, all or a combination.

The entitlements, however, may cost 10s of thousands.Once there's interest, things can be adapted to fit whatever tenants want, for instance combining two pads with 2000sf restaurants into one pad for a 4500sf restaurant.

Then there would be an advantage in being able to have "spun off" a portion as investment and combine the two.  

Just couldn't justify the $200/mo at the time I reviewed it.There are a lot of other options out there such as Buildium that might suit your needs.I currently own/manage 31 units and use a combination of Excel, Google Drive, OneNote and probably a few other freeware programs.  

For three weeks, we went back and forth through email (I didn’t even have access to a phone this entire process), which largely consisted of her threatening to sue me/withhold rent for whatever was her complaint du jour, followed by me attempting every placation strategy I could think of.

Like others have touched on though, we were working on it up until move in day but just little touches here and there, washer/dryer delivery, etc.
