I currently have a house I am renovating that should be worth around 210k-240k and rent for $1,800 - $2,000 in May.

The mechanics of the transaction were actually very involved and some of the most intricate and detailed of any transaction I've been a part of, however the results were worth the effort.

I won't pay more than what it's worth to me, regardless of what someone else paid for it.

I filled up 4 dumpsters worth of trash, old carpet, furniture, and whatever other horrors the previous owners left behind.

Help me see if this is "worth it" or not.  

Meanwhile, gross rents of $1,800+ for 3-bedroom single-families is an achievable figure, so it’s possible to generate cash flow if you lever modestly.There’s a bunch of other stuff that’s worth highlighting—the economy, demographics, neighborhoods, new construction, and more.

Zillow is saying the house is worth $90k but recently a tree went through the back end of it and I was hoping to get some information on possible ideas or suggestions on what I should do about the situation.

Do not bank on setting a new neighborhood record on $ / sqft - be conservative in your numbers.

You don't provide enough data to know.Every product is only worth what you are willing to pay for it. 

For a land cost of $150k, how would you think about how much the completed home would need to sell for to make that land cost worth it?
