I just trying to estimate how long it will take the the heaving to settle once I repair the leaks so I can start rehabing the house.   

Some pros:- You'll have plenty of cookie-cutter comps so you should be able to get a very accurate estimate of ARV and/or sale price in the case of a flip.- Your maintenance and repairs will be mostly limited to the interior of the property as the condo management will maintain the building- You won't have to worry about tenants maintaining the grounds around the buildingCons:- Condo fees may change drastically over time and it's largely not in your control- Condo bylaws can be tough to work around.

Now you might be like Joe, know rents for a couple of neighborhoods and can quickly estimate expected cash flow from properties pretty quickly (that's what I do as well) but you still need a screening rule so you invest minimal times on properties you will never put an offer in on. 

"In a 2016 paper, Mark Zandi, chief economist at Moody’s Analytics, estimated that full privatization of Fannie and Freddie would cost the typical American taking out a new mortgage $1,200 annually.

I bought the property at $365k, and its new *estimated* value after renovations is 390k-400k.

Is there a place where I can type in the address of the properties I am considering, and it will spit out an estimated monthly rent? 

I estimated this to cost me $300,000 to scale.

He only gave me an estimate (doesn't show work completed) for $5,000, even though the repairs were stated to cost $15,000, he said he lost other documents, when I ask him to retrieve them or allow me to retrieve them from repair company he won't.

My biggest two cents is no one should flip unless they are the best at estimating ARV in their room--better than the appraiser, agent, lender--when that happens, your deals will fall into line. 

., I estimate that this will cost over $10k.
