These methods involve securing financing, identifying suitable properties, and overseeing renovations.

For Airbnb guests, the process differs from the traditional eviction method used for long-term tenants.

The BRRRR method is a great way to quickly build up a rental portfolio and considering you are in one of the fastest appreciating markets in the US, you will be able to profit off of appreciation as well as rental income.I am a real estate agent for off-market distressed properties here in Fort Worth, Arlington and surrounding areas.

Personally if you are looking to grow in real estate going the traditional method/way of getting good properties under agreement with traditional financing will get you to where you want to go faster than trying to find all the needles in a haystack.

Cost segregations, bonus depreciation, etc.....are just ways and methods of writing off more or less at certain times.

Whichever method of lead generation you decide on, aim to establish and maintain a relationship with prospective sellers. 

Small roof repairs are usually fine to do, but ... the foundation should be corrected and settled back in place (usually 1-3months, depending on the method and what was done) before the roof is replaced, or you'll void all warranties that the roof had!

If major foundation work, you should wait 1-3 months to do the full roof replacement (depending on the method and how much was done).Example: If/when we do a full residential roof replacement, if major foundation work is done after that, any/all warranties are void!

As far as value add there isn't any one particular method I'm partial to. 

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.
