The two that interested me most were the CAM Designation and the IROP Designation from NAA.

I've cam up with a $280k ARV because to properties on the street and block sold 7 months ago for just of $300K same style, rooms and similar sqft, only major difference is the house I might be possibly rehabbing has only 1 bathroom and the rest that sold for just over 300k has 2 bathrooms.

You cam to the right place! 

While this thread has some age, my plea for assistance revolves around four vacation short term rentals with only the use of VRBO/HomeAway.

Life always seems to revolve around houses.I have been interested in real estate for a long time, seeing a great aunt rent the house next door and talk about how the rent check covered the mortgage on the house and part of the taxes on her next door house, which I though was incredible especially as I grew older and learned about the tax benefits of owning a house and rental house.  

Sean Terry interviewed him on his podcast #64, a very thorough discussion of his method which revolves around marketing to landlords  (a very saturated group nowadays).Anson Young talks about it in his bp podcast and Rob Swanson has a course on it that I haven't seen but he's interviewed by JP Moses on Moses' website. 

My question revolves around peoples' opinions on how to best prepare myself to invest in income producing properties in the next 3-4 years in regards to 401K v IRA v highly liquid personal stock portfolio.I have read many posts on here referring to using self-directed traditional or roth IRA's as the vehicle through which to invest in real estate, but I am curious if I have not yet started a roth would it be better to start a post-tax savings/ investment account so that I can be ready to jump on a deal nearly immediately if one presents itself?

Finance is absolutely nothing these days.Buying a car should revolve around the impression you want to set when someone new meets you.If you turn up in an old car, you look poor, no matter how much "I spent $5k on this and I own it outright", that will not balance out the shock of seeing you in some old Ford when you are presenting yourself as a hotshot investor.

We have one long term tenant who has had a LOT of different people live with her, it is easier to make the revolving roommates authorized occupants.This is the clause we use to designate the primary tenant and give us more flexibility:In the event that Tenants decide they no longer want to live together, ___________ will be considered the primary Tenant to make decisions about modifying or terminating tenancy.

My vision is larger than my fund, and revolves around ensuring that those who live in marginalized communities have access to the social determinents of health (education, economic opportunity, healthcare, and homes) and are able to get themselves on a pathway to generational wealth through home ownership.
