Then you send a letter to the dr and ask is she a patient? 

Nobody can predict when and how the market cycle will drop, but leveraging yourself up that much with minimal/no cash reserves and no REI experience at a time when the market is already very heated is a risky proposition and one you might want to consider building in a little safety net before jumping in. 

Deals will always exist, opportunities will come, be patient.

Challenge: Seller not negotiating even after inspection report showed areas needing immediate attention (for safety reasons) Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Also I recommend “house hacking” as a first investment due to the safety factor it provides.

What would be a good capitalization range.I assume there must be some rule of thumb like [Purchase Price] * [%Down] + [Closing Costs] + [Some Safety Net] = RequiredCapital before purchaseIs there any advice out there for a newbie who fears jumping into a deal undercapitalized and being ruined by the first big expense while also trying to get into the game ASAP?

Just need to be patient I suppose and keep looking for good deals.

Notwithstanding, we as investors must put in place several important safety clauses to protect our interests.

Simple things like inspecting properties regularly for safety hazards.

If you're patient, a lot of things are possible :) Yes, I think you could build a great portfolio.
