@Patrick Shep I would absolutely encourage you to apply without any co-signor.  

I've been going to local RE meet ups and talked to other investors who have used many different strategies: out of state, syndications, NNN (triple net), commercial, AirBnbs, mid term rentals, co-ownership, house hacking, etc.

We can't really give you a detailed amount of help with out more.Is it in Aurora, CO?

I’m curious about the pros and cons you’ve found with each approach, especially here in Colorado.

This is networking, tapping your current list of friends, family, co-workers, other real estate investors, etc.Ideal duration depends on business plan: I, personally, am a fan of long-term fixed rate loans.  

For both the applicant(s) and a co-signer, you want to understand their habits...financial, employment, legal, character, etc., as Bad habits in one area typically carry over to other areas, and will land you a poor Tenant (or co-signer) choice.

Kind of reminds me of a book I read by Steve Case (AOL CO-Founder) called The 3rd Wave. 

Learn the business (and by that I do not mean assist  diligence on another GP's deal for free and get awarded "CO-GP status" to run with).

I haven't worked with anyone since we prefer co-hosting but know oodles and oodles of hosts that do it.

SOS......I closed on my investment property last Thursday, lawyer, title co, realtors paid and keys handed over to buyer but the wire from the bank ( the title company uses) keeps getting rejected by my investment company.
