Quote from @Chris Seveney: @Francisco AvancenaThere are specific lenders who will do land dealsBut of course not as many as traditional real estate.The key will be skin in the game - typically for land because it is less liquid than a home the lender will want to have a lower ltv on the deal I fund land flippers currently in  CO FLA WA ID MT NV AZ OR TX SC GA VA  one thing about land though LTV is lower and RATES are NOT the same as typical HML rates are higher for raw land but its a specialty niche and a business that I grew up in..

W what typically went wrong in your case? 

Without reserves, they might be unable to evict tenants or prepare the units once they are vacant.

Bogleheads was the source of most of my formative personal finance education (for ~14 years), and it’s relevant because the SWR discussions there are typically in the 2-4% range.

Typically on old houses it's cheaper for a seller to put vinyl siding over old asbestos boards then replace and ripoff.

Agents and Lenders are typically a little more available than a good PM or Contractor.

I'm in Los Angeles, and the most I can pay on flips is typically 60-65%.You want to get recently sold comps to value the property, it's the best way to be sure of the value.

Typically speaking we leave out front/side exterior photos on every listing, regardless of grandeur.Years ago there was a rash of thefts in South Florida where people were finding houses based on map and exterior photos and breaking in when vacant and clearing them out. 

This contrasts greatly with most accountability partnerships, as a mentor is typically more respected as an authoritative figure.

Yield varies a lot depending on the type of property and location. rental yields for residential property are typically between 4% and 5% per annum.Hope this helps!
