I suggest using a service like Mayistay.

You can read a book and multiple books, but unless you are out there doing it (I.e. getting bids and getting contractors to truly get you an exact estimate) you will be far off from the numbers you want and may even lose money on the flip/rehab.The best advice I would suggest in my experience is that you should get into the line of work by either partnering with someone or working with someone on some projects prior to going into a flip on your own.

I’d like to buy the place, renovate it, and then live in it for a few years as my primary while renting out the 2/1, and then ultimately selling or renting out the main house too. wondering what the best purchase strategy would be considering I don’t have the full purchase price in cash on hand?

I assume your question means you already have a 600k property that you owe 420k on, and are wondering if you sold that property to buy more properties which way would you come out better over time. 

Could you kindly suggest the best resources or methods to identify comparable properties in the area?

I'd suggest making sure to get a good GC/construction company for repairs.

Quote from @Sofia De Santos Tavarez: Hello, my husband and I are looking to do our first rehab in a different city than where we live (we live in Austin and looking to buy in El Paso), and are wondering how one determines and writes a scope of work and determine what material to buy for what.

I'd also suggest considering a partnership if you feel comfortable with that in order to reduce the risk completely on you. 

Hi I am a current homeowner and want to get a 2nd property for short term rental.I am wondering what would be the best course of action in terms of getting a loan for an investment property.Would you recommend getting a FHA loan or other conventional loan and living in the property for 1 year before renting it out and then renting out our current home or getting an investment loan and start to rent out the investment property?
