(so the taxes would be lower) I'm reading a book by David Greene about the "brrrr" method.

Who's utilizing what methods from home? 

Also Alexander Felice wrote an article about the Delayed Financing Program in which you can refinance sooner as well. https://www.biggerpockets.com/blog/work-with-lenders-brrrr-method

I have been learning so much and different methods and creative ways through tons of reading and podcasts and I want to get started on my first deal.

As a data provider, I have been toying with the idea of offering blast text packages along with data...I'm curious as to how often investors utilize non-postal marketing methods when hunting for properties to buy. 

I am a new landlord and looking to find the best method of collecting rent?

Borrowing the down payment from someone else is a method.

Is this a worthwhile finding method?

Negotiate with the seller (solving their needs, first) and get it under contract - with the right contract. 

I use both as a RE investor between commercial and residential as both can be used on 1-4 unit properties (non owner/investment occupancy).The pro's of commercial/portfolio financing from local credit unions and community banks are that you can:- talk to a local banker/lender who is interested in building a relationship with you over time and is flexible to make a loan as long as its financially prudent and you show a track record- ability to build a track record with- less documentation scrutiny than a fannie/freddie conventional loan which is more ridged because it needs to be sold to the secondary market so all boxes must be checked to do so (otherwise the loan is unsellable or undeliverable)- is cashflow based via debt coverage ratio or DCR method of qualification (Net operating income / debt service) - can fund to LLC's, entities, and businesses with personal guarantee (PG) usually- can do unique loans like cross collateral or blanket notes across an entire portfolio, can do rehab/construction + permanent financing into one (one time close products), can do soft liens and releasable upon progress on your projects so you can leverage equity with temporarily encumbrances, unique disbursements on credit facilities,etc Hope that helped compare the cash out options.
