To find out the annual percent I multiply the 1.67 x 12, correct?  

Start with the current lot rent (ignore the POH rental if there are any that come with the deal) and multiply by the number of spaces that currently have a tenant paying rent.

So for example, to calculate the payment on a HELOC of $300k, you would multiply the APR by the loan amount and then add that to the principal and divide by 360?

Small multifamily you can use Gross Rent Multiplier to ballpark an ARV (a local lender can help you get that number), or the cap rate which is the most likely to be used to value anything commercial. 

If you can find some good rental properties that will not impact your DTI ratio (generally speaking this is the case when rents multiplied by 75% covers your PITI) then that $175 could lever up to 875k in rental properties which is really strong.   

These two other parts determine rate and loan to value.No mortgage lates, no forbearance, take all the bills on the credit report and multiply by 12 or 24 for the cash reserve piece.Minimum loan amounts are being enforced as DSCR rates bump against  High Cost loan laws when the loan is small as the floor of fees is the same for $70000 or $200000.

The 75% is multiplied by the gross.

IE multiply by 0.3 not 0.7.  

If anyone else is thinking of trashing me for simply wanting advice, please move on.Eh, divide the monthly rent by the number of days in that month, to get a $/day, then multiply that by the number of days you had no utilities.

Than you simple take that known cost today, multiply it by an inflation rate for the amount of time left, and now you have your "budget" for that item.
