That's why, its best to shop for quality lenders. 

You need to have sources (agents, wholesalers, GCs) that bring you opportunity that they have mined and they are bringing it to you cause they know you buy.To the vendors of the industry: Agents, Wholesalers, GCs, PMs, what have you...you are nothing until you buy something, until then you are window shopping. 

It amazes me how much random transient travel it gets(bowling tournaments, pawn shop remodels, manufacturing employees, traveling photographers, etc). 

The best way to find a handyman is to look for business cards at coffee shops and local restaurants.

We syndicated 75%, plus costs of the purchase price and financed the balance with a traditional loan.We shopped around for weeks to find the perfect loan with the best rates and terms.

Quote from @Steve Tse: Hi BP, What insurance carriers can you recommend in Texas, as I am shopping around to replace my landlords policy that I currently have with Travelers ?

Shop around with local lenders, ask these questions, and get answers before you try to buy the triplex. 

A broker can shop dozens of providers for you.
