I came across sites such as mashvisor and airdna which seem to be provide solid information for novice investors like myself.

@David MoreheadJust my 2 cents, but there isn't anything in any of these seminars you can't learn in a few weeks for free yourself (or by buying 2-3 books for around $10 each + reading free info on sites like BP).Not trying to talk you out of it, but for $10k you can actually buy a rental property in some parts of the country, so I would seriously consider the value you're going to get.

A good site I use for research is municode.com to find out all the local regulations we might encounter and if there are specific building standards for Parks.

This site and community has changed my life!

The calculators on the site are great for asking you the questions about things you may not be thinking about yet.

I grew up working on job sites, so am handy myself. 

. - find other equity investors to partner up with you- in a pinch, you may be able to get (expensive) personal loans and LOCs through sites like lendingclub, sofi etc..

To address your cap limitations, there are lenders that will have specific low down buy and live in programs with competitive interest rates that allow you as an owner occupant to finance a 4-plex as long as your live on site for a full year.
