When I retire, SOON, God willing, We will be taking about 25-30k a year out divided up monthly, and leaving the rest for reserves and expenses.

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.

To calculate DSCR you simply divide the NOI by the total debt aka loan payment.For example suppose the NOI is $120,000 per year and total debt service is $100,000 per year. 

Divide the net operating income by the cap and you have the value.

@Michael PlaksI understand that the amount of gain eligible for the §121 capital gain exclusion is reduced in proportion to the total period of non-qualified use divided by the total period of ownership.The point I am trying to make is that the total ownership period begins on the actual purchase date and ends on the day before the settlement date of the sale.   

The difference between $50k and $60k for one seller is significant; when that's getting divided up 5 ways, it's the difference between having $10k now and hoping to get $12k later.

If you divide by your down payment of $16,342, you would be earning 12.4% cash-on-cash return your investment.  

They don't go inside the comparable apartments used in the appraisal.2) Creating an additional bedroom by dividing a large room, closing off a dining alcove, etc.3) This is out of my wheelhouse but I would say mortgage recording tax and title insurance but you can avoid much of the recording tax by doing a CEMA.

If I divide this bill by four units, each tenant would pay $46.03.

Mainly you can divide them into two categories: 1)  Deduction for AGI. 2) Deduction from AGI ( if this is less than 24k, you would take SD)I cant give you entire list as it is massive.
