It started to snowball from there.The second contributing factor is that I have begun buying rentals again.

I figure if I dont factor in cashflow for right now, the numbers work, and I assume rent increases by the time I plan to rent it will give me my desired cashflow.Please just help remind me what steps to take and what not to forget...

financing is the biggest headache I deal with,,most of the guidlines you are talking about aren't with the bank, but with Fannie,, some of the rules make no sense,, and one mystake can make it so that you can't go conventional, but there is always a portfolio loan from a bank (a loan they don't sell), but you won't lock in the rate for 30 years

most hard money loans are interest only, and most I deal in are 6 months, interest paid monthly.they will loan me 70% of the after repaired value of he home,,,so if its a home that will be worth $100k when I'm finished, and I'm paying $65, and it will cost $10k to rehab,,then they will bring $70k to closing, I will pay closing cost plus the other $5k ($65k+$10k),,they will then escrow the rehab money.You will also have your signature on the loan, and they want you to have decent credit

These are 4 two bedrooms ideally, but often a mix of 2's and 1's.

Yeah, I always factor AC/heater, foundations, or roof repairs separate from the rest of the costs, as they completely change the game.

*Can anyone provide some solid, successfully traditional mathmatical formulas & some key strategic factors when analyzing first time multi-family properties?

It really depends on hundreds of factors.

These are the key factors you need to be sucessful in the model you propose.In addition, simultaneous closings (where you use your end buyer's funds to close your purchase transaction - using buyer C to close the A-B transaction) are very difficult at best these days due to the many law changes and the title companies not insuring the transactions or willing to perform such transaction.

I dont have a strong understanding on "delinquent condo fees" and how that plays a factor in investing in a condo.
