A HELOC can be nice, because it enables you to act quickly. 

I have a full-time employee finding deals for me and a bunch of other sources which enabled me to complete a dozen flips and to buy 41 units so far, but like everyone else, I always want more and I want to find ways to increase volume.Thanks a bunch!

I understand from other discussions here on BP, that the IRS may have very stringent requirements for REI's claiming Professional Status to enable RE losses in excess of $25,000 per year against non passive income.One suggestion, in addition to detailed records of the over 750 hours of RE activity, is the "Election" of combining of all your RE properties into a single entity.I have not found a way to do this in Turbo Tax (no chuckles please).Does anyone have experience with this and discuss the pros and cons of such an "election."

@Frank LaQuagliaIf your goal is to spend the least amount of capital, then compiling your own list from D4D, going to your assessor's office, and other means of doing the work, and printing your own mailings in house will cost the least.If your goal is to scale up and do decent amounts of mailings to have a solid pipeline to enable consistent deal flow over time, eventually you're going to want to outsource the your print/pack/ship of DM. 

I am hoping that my joining the Biggerpockets community will enable me to create the marketing and investing network I will need for my business to succeed. 

You can pick someone who's (A) attentive to your needs, (B) very knowledgeable about the area, (C) not just trying to sell you any house.Technology to enable the teamI use Google Sheets to track all of the properties in play with my real estate agent.

This enables you to defer the payment of your ordinary income, capital gain, depreciation recapture and/or Medicare Surcharge (“Obamacare”) income tax liabilities.There are important timelines and rules you must follow in order to successfully complete a 1031 Exchange.  

This enables you to vet the information provided by the Vendor with the Tenants and/or Service Providers (i.e. leased water heaters, HVAC, Laundry,  landscaping services, etc) to see if the views of the relationship terms align or not.

Here are the stats:Current payment and rate: $1,807.23 w/4.75% rate 30 years at 4.25%: Savings of $230 monthly with MI 15 years at 3.5%: $1,868.83 (w/MI)15 years at 3.625%: $1,821.84 (w/MI financed)We can comfortably pay our current mortgage amount as well as the 15 year options, though part of our reason for refinancing is to enable us to eventually move and rent out this property (better cash flow), however now I'm considering is there more benefit in doing a 15 year and building more equity that can later be used to do a cash out refi or HELOC?

You could get a Solo 401k plan that enables to invest in both RE and the stock market.
