Here are a couple of numbers I use -- and many other investors too -- although others may prefer to tweak the percentages a bit for their style or individual market.Flips or rehabs --  Take the After Repair Value of the home (ARV) and multiply it by 70% and then subtract the rehab.

Gross Rent or Gross Income Multiplier to assign value? 

@James M.Everyone's tax situation is different and likely why income taxes are not factored into rental calculators.With that said you can roughly estimate your taxable income from rental activities asProjected Income less projected cash expenses(not including principal) less depreciation multiplied by your federal and state tax marginal tax rate.

If so, simply multiply the salon’s expenses by 3.

If you can find out what they rent for nightly throughout the year and then multiply it by the yearly occupancy rate you can get a pretty good idea of the yearly income.

Anyway, after multiplying that by months and years, it really looks like a great opportunity for an awesome return.

If you buy value add properties you can refi and deploy the equity back into other properties once you increase the value and continue to grow.You could also use that cash to flip, build spec houses or do a small development project and multiply it much quicker than you can buying cashflow properties. 

Here are the specs:-40 lots, I understand trailers are all owned by tenants-$350 per lot-10 acres-most homes are newer and well kept-outside city limits on well water-large central sewer plant-park is owner managed, his overhead is 25% but he is jack of all trades-owner told me he had appraisal within last few years and value was $1.5 million then-room for addition of at least 20 more lotsI have seen formulas online using a multipliers  of either 60 70.

If i own a Multi Family, i can claim the exact same write offs however they would only be the exact same, not multiplied by 4....

From the syndication opportunities I have seen come across my email they are generally 5 years or so in length with CoC average returns of 8%+ per year PLUS and equity multiplier GREATER THAN 1.
