However, whatever definition I come up with or have heard seems to have exceptions that make any hard and fast label difficult.

John - You set up the blog categories from your Blog's ADMIN at the top right of: http://www.biggerpockets.com/blogsAs for where it says "Mobile Home Investor" that is determined by the PRIMARY label that you set to describe yourself on your EXPERIENCE tab at http://www.biggerpockets.com/profile/experience.We do not have a category for "Mobile Home Park Investor" however.

A few considerations though:70-80% LTV is NOT conservative right now, especially if this is residential real estate; you would need to be <70% LTV for the "conservative" label IMHOIf you are talking multifamily or industrial (not some of the other depressed CRE or fix-n-flip residential) with the equity conversion, that might just appeal to investors, otherwise bumping the coupon would be where you need to be net returns wise.

Not that those labels are completely wrong but just that within one zip you can EASILY have A, B, C and D.

It is labeled Fix & Flip | Nov 2014 - Oct 2016Single-family residence in Beverly Hills, CAPurchase price: $1,890,000.00Cash invested: $450,000.00Sale price: $2,575,000.00That was my biggest failure where I lost about $250k!

Latest flip, we had flooring ordered and paid for, then it sat in a warehouse (with the fedex label created) for over a week (was supposed to go out within 2 days of order).  

I learned that in order for my investing business to be successful I needed three important ingredients: (1) Money (2) Quality contractors (3) Off market properties.That led me to concentrated on finding deals that the numbers worked within, even with rates at 12%+ and up to 4 points for short-term money, and in areas where quality contractors wanted to do work.

I remember one investor who labeled himself "sarcastic Asian guy" because his humor was dry and he knew people needed a prompt.

Label where the bedrooms in the pictures are-in the main house, the back house, upstairs?

The FCA definitely has a way for an investor to demonstrated that they are a Sophisticated Investor (UK's label for accredited) if the investor has been active with unregistered securities.
