The CapEx estimates can be very difficult to estimate without seeing the building.

I wouldn't depend solely free advice and on contractors' estimates, although there are certainly reputable ones available.

So how would I go about getting a contractor to take a look at a property and estimate the rehab cost?

Below are the details of each property, including purchase price, current estimate, and equity, along with their respective cash flows:Home 1 - Condo, (2 BR, 2 Bth)  Fayetteville,NC-  Purchase price $50,000 - Current Estimate $75,000, loan amount 0 = Equity $75,000Cash flow - Rent - $825, PM Fees $75, HOA Fee $100, HOA Assessment $163, Taxes $50, Ins $25, Loan Pmt $0 = Cash Flow $412Home 2 - Condo (3 Br, 2 Bth) Fayetteville,NC- Purchase price $89,000 - Current Estimate $155,000, loan amount 0 = Equity $155,000Cash flow - Rent - $1250, PM Fees $112.5, HOA Fee $231, Taxes $90, Ins $30, Loan Pmt $0 = Cash Flow $786Home 3 - SFH (3 br, 2 Bth) Little Rock, Ar - Purchase price $189,000 - Current Estimate $300,000, loan amount $85,000 = Equity $215,000Cash flow - Rent - $1500, PM Fees $150, Taxes $269, Ins $156, Loan Pmt $766 = Cash Flow $159Home 4 - SFH (3br, 2 Bth) Abilene,TX - Purchase price $225,000 - Current Estimate $315,000, loan amount $51,600 = Equity $265,000Cash flow - Rent - $1850, PM Fees $185, Taxes $583, Ins $145, Loan Pmt $1400 (0 Interest) = Cash Flow -$463Total Equity = $710,000Total Cash Flow = $894Sell, Sell with 1031 exchange, Cashout Refinance, HELOC'S...Too many options, i don't know what to do.  

@Charlie ZelayaDo you know how to estimate an ARV using comparable sales?

Unless it's in really bad shape, it's usually worth it to get 2-3 real estate agents to give you a market analysis with estimated seller net (even if you're out of state, they can email it to you) so you can compare before you agree to sell. 

The calculations provided are estimations and could vary based on specific loan terms, tax implications, and market conditions in both Kentucky and Florida.

Our ultimate goal is to locate a property that makes sense from investor's point of view, that has verifiable ARV, accurate estimate of repairs and right price for a buyer to profit from it.

I was thinking perhaps it would be easier to just bring a general contractor to walk the site and provide an estimate on all the rehab costs, rather than to find separate contractors for each specialized task.For those of you who have worked on fixer-uppers, did you bring a general contractor to walk the property with you and give an estimate on rehab costs?

Start with learning how to run comps, how to estimate repairs, how to find deals, how to negotiate with sellers, reading and understanding a purchase agreement, finding an investor friendly title company, having an attorney create an assignment agreement for you, contacting investors to put on your buyers list etc.
