I've looked into mobile/manufactured homes as an option but with lot rent it seems like it may not be worth it.

Consider single-family homes or small multi-units to learn the ropes.

I am currently working on phase 2; building 2 ADUs.The permits are already in the works but the biggest question is what is the best approach when funding these 2 ADUs BEFORE I have the equity from my home?

My ultimate goal is to become successful with my real estate investments so I don’t have to rely so much on my job and be able to spend more time at home with my soon to be wife and future children.

Quote from @Kris Kempe: Hey BP fam, Have a single family home I got under contract and planned on wholesaling.

Common sources of such properties include:Foreclosures: Homes that have been repossessed by banks due to non-payment.Distressed Properties: Homes that are in poor condition and need a lot of work.Auctions: Properties sold at auction for below market value.Off-market Deals: Properties that aren't listed on the MLS but are available for sale through direct outreach or networking.The key is to buy a property at a price low enough to ensure that even after renovations, the home will appraise for a higher value.2.

Considering most homes will not cash flow with 20% or less down, plan on 20% and most likely 25% down required - depending on the cash flow expectations. 

FHA loans require living in the home as your primary residence for 1 year after purchase.

I toured the property when they were home and they asked me how the living situation was gonna work, which I explained that my loan said that I had to live on the property for a year, and the tenant next door was on a year lease & he was month to month... so he was going to have to leave.

There is no point in looking at a home that can not reasonably obtain a permit.
