@Sergio Rodriguez, one way to quickly check the trend is to take the trailing 12 and compare the T12 numbers to the T3 (last three months, multiplied by 4) to the T1 (latest month, multiplied by 12).

If your jurisdiction only allows you to use your rent multiplier on only the tenant portion of rent, then change your criteria to a flat amount instead of using a multiplier. 

Make sure you are a rockstar at sales - doubling your close rate on cold leads can be a nice multiplier on leads.

Each property will be written up seperately so I won't have to pay the loan in full if I liquidate a property.So I asked if the fees multiply by the number of properties I leverage.

.$450x3units = $1350 monthly incomehowever it is a 4 unit, so it should be $1800 monthlyit was called a "gross rent multiplier" of 15...

Try to use the "rent multiplier," which your agent can help you determine. 

general rule of thumb for most parks are lot rent * # of occupied lots * 12(annualize)=Annual Gross revenuethen multiply that by .6(if park pays water/sewer) or .7(if tenants pay water/sewer) to establish you NOI(net operating income).  .6 and .7 are for 40% or 30% operating expenses.Then divide that number by your cap rate you want, most people use 10% cap rate so .10 and you get your purchase price.

A quick and dirty valuation based on a commercial appraisal is a 100 gross rent multiplier, which is really just the 1% rule stated another way.

@Joe CassandraYep, that's generally how parks are valued - Lot Rent Stream as one separate valuation / POH as separate.In my spreadsheets, I separate the income / expenses for the two different portions.So if you're paying $2000 / mo to a maintenance man and he's spending 75% of his time fixing homes, then $1,500 is going to the POH side of things, and $500 to the Land Side.With the RTO stream, you can use a net present value formula, where you take all the anticipated cashflows, discount by 25% due to people bailing, etc, and then discount that income back to a rate you feel comfortable with (ie. 15%).That will give a theoretical value for those income streams.With POHs, here's what I've seen people do:Value based on what you can sell them for << more commonValue based on a gross rent multiplier, typically 1-3.

if your new loan amount, the appraised value multiplied by the LTV, doesn't at least cover what you owe the orig seller, then you can't refinance, much less cash out refi.
