I have 4 long term rentals in my portfolio and I am mainly focusing on investing in single family homes in Traid, NC. 

This could mean investing in property flips or purchasing out-of-state rentals for more stable income, but it would require letting go of the $1,350 rental income from the manufactured home.What factors should I consider for each option, and how would an experienced investor assess this situation mathematically?

The first is the way dividends or rent is payed is through tokens which recently have been under pressure due to their transaction cost, it's not a deal breaker but it is something that factors in when you go to turn your tokens into money.

For me, I wanted to portray my real estate investments as more professional and that was the main reason I switched to using landlord software for rent collections. 

Keep in mind though that your return on equity on your 400k equity goes from 1.5% right now (assuming 500/mo positive cash flow) to getting a -3% on the remaining 200k in equity, so that is also a factor.

The main reason I would like to start off my career with flipping a few properties is so I can have a quick ROI and I want to do real estate full time as soon as I finish my contract.

My main goal is to invest in real estate in the future, but I want to understand how everything works first.

When networking on BP or in person, being clear about your goals will make a big difference.Are you mainly interested in finding rental properties, connecting with other landlords, or exploring specific asset types?

The other motivating factor here (for me) is that I want to move my mom into one of the units so she's close by.

My opinion is that the overall direct effect of immigration policy on any given market will pale in comparison to other factors such as the economy, inflation and deregulation.
