Z Loraine Nielsen Its up to you if its ok.

@Priscilla Z. runs a local meetup, and a number of us in the county spend the 1st and 3rd Monday of each month chatting about the deals that we are doing.  

I do the same, as I much prefer to see I have x for car emergency, y for truly dire straights, z for medical, etc.

The seller will typically carry said note for Y amount of time with an interest rate of Z.So transaction would look like this:Agreed Purchase Price: $ XDown Payment Amount: $ DPBalance of Note Carried: $X - $DP = $Note BalanceTerms Y years at Z interest rate Amortized = Monthly Payments (Principle + Interest)Optional (Add in Escrow Account for Taxes + Insurance)Some people also use a servicing company and add a monthly Servicing Fee for that.So the final monthly payments would include P+I+T+I+SF (Principle + Interest + Taxes + Insurance + Servicing Fee) Also, if you sell more then 3 homes per year to owner occupants with seller financing, you have to use a Mortgage Loan Originator to be Dodd Frank compliant. 

Coming across sounding like you know what your doing is very different than actually knowing the entire process from A-Z.  

I noticed also that there are no calculations for CapEx, Repairs, PropMgt, Vacancy, ect, which would also increase your overall negative debt.In the words of Hip Hop artist Jay Z: "Men Lie, Women Lie...Numbers don't"

(google 'how to make a range in excel')then =sum(x+y+z)=earnings/budget

Originally posted by @Martin Z.:$400 for each unit is great for sub-metering, but then you have to collect the data most likely manually.

I remember calling people for my first property and hearing all sorts of different stories from different lenders, "SORRY, NO ONE does that, you HAVE to do x,y, z."
