And they multiply that by trying to scale rapidly thinking riches are in sight and the coming apocalypse in many parts of the country where regulation changes and rapidly increasing competition from other Airbnb wannabes or hotel chains, and other things that will grind down occupancy and rental rates.

You can find your ballpark purchase price by taking what money you have to invest and multiplying by four.

Multifamily and commercial loans are not 30 or 40 years they are often due in five years and you keep re-qualifying and refinancing." so I need to multiply the cash flows yearly by 5 years and check if it is the same price as the property?

Multiply and expand.Look at each asset as a business.

You know that leveraging (without going to 80%+) somewhat will multiply what you can do.

If I have to negotiate labor cost with someone whom I have never worked before and that person couldn't give me a labor price up front, I would say: "To me, this seems to be a X day job (feel free to use half day), (in your mind, calculate the hour x hourly rate = Y dollar amount, make sure it's man-hour or man-day so if it's a two-person job then you need to multiply by two for the same time period) does $Y work for you?"

So it does not return too much cash flow from an income stand point, but by having a 5% cap rate this in essence means that every marginal dollar of NOI $1 added per month can create a multiple of 20 times in value ($1 / .05 cap = 20) or if multiplied by 12 months in a year, $240 dollars of value in equity.The 10% cap in rural indiana with the same terms as above would have a monthly cash flow of $8261.95 or approximately 22.8% cash on cash return with out factoring depreciation, appreciation, or amortization.10% cap = 10 X multiplier of Net Operating income or NOI so each dollar you can "net," per month by either increasing income or reducing expense creates $1.00 X 12 months X 10 multiplier = $120 dollars of value in equity.So the difference is in how the market cap affects your ability to create "equity," with the lower cap rates you dont need as much increase to create that equity while in the mid west since the cap rates are higher (lower multiplier) you'll need to have in this case double the net income creation to fabricate the same amount of equity growth as in Seattle.If you're trying to reposition and sell for profit, a lower cap market can be better if you find a troubled property with an opportunity to force equity in Seattle since the value multiplier is much higher, 240x.The rural indiana property with a higher cap rate could allow most to live financially free ($8261.95 cash flow per month) while offering a lower 120x value multiplier to create/force equity.So it all depends on your strategy to focus on equity or cash flow and to recognize which "play," you have in front you and whether the juice is worth the squeeze for you personally.

So look up the comps or have an agent look up the comps and figure out what the price per square foot of the comps are, and multiply that number by the square footage of the subject property. 

wont judge anyone, but frankly sometimes all we need is a little faith and some  action and God can multiply our efforts.

My dad is a Contractor..They add the Materials of how much is it..then He multiply that by four..if the material is $1k labor and materials will be $4k
