At the end of the first quarter I am sitting at $109,500 in buying 4 properties either outright or on contract.My goal leaves $890,500 worth of value to be created in the next 9 months.

If the 1031 falls through, the estimated tax becomes due from the seller that quarter (I don't think you can wait until the next April), but obviously has to be paid direct and not through the escrow because there will have been no money posted at closing.

Now, if you do proper tenant screening and quarterly inspections yourself you should have a great cash flowing vehicle.

This is what you generally get with a property manager:- a licensed professional who completes ongoing education and stays on top of new laws- Someone to handle all maintenance requests, complaints, tenant-tenant issues, and communications- A routine inspection ensuring the building is up to code- A quarterly report showing the life cycle of all assets, roof, bricks, windows, a/c, heating, etc.- Troubleshooting any maintenance issues or building upkeep, gathering estimates from multiple vendors when there is a larger repair to be made- Following up on all repairs & maintenance that was done to ensure it was handled properly

have you every heard of doing this quarterly or is it just overkill? 

@Chris LawrenceEveryone's costs will vary when answering this question.It will depend on how many separate bank accounts/credit card accounts are being reconciled.It also depends on how many transactions occur.Furthermore, it depends on how often you want the books done for you.More accounts = more costMore transactions = more costmonthly bookkeeping cost > quarterly bookkeeping costs.I think that $250/month based on your situation isin't super high or super low considering you have flips and its harder to do bookkeeping for flips. $250/month sounds about right.

Quarterly inspections are a good way to record damages and make assessments. 

Though I don't use an LLC for rentals, at the time I got an LLC for a business, have other businesses in S-Corp and C-Corp, with employees, quarterly withholding tax, workman's comp. unemployment insurance, annual federal and state returns so I don't need a few extra set of books, 5 more LLC's for rentals, which is totally redundant. 

I certainly would not call it a plan anymore than I call tossing a quarter into a wishing a plan.
