We are considering the following options:-I purchase the property from my aunt – Perhaps we can do seller financing to reduce fees?

Purchase price: $75,000 Cash invested: $600,000 Sale price: $269,000This is my largest new build development to date.

The second is a rehab property that I purchased for myself, I purchased it out right for 100k.

Typically starting with a smaller rehab budget of $50K or less (maybe a max of $75K) and avoiding a 1 to 1(or higher) ratio of purchase to rehab costs is recommend when you are first starting out. 

Purchase price: $425,000 Cash invested: $5,000 ell after just 6 months of owning.

@Rosette PooleRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

I have a unique plan for getting ADU's done quickly and economically.

In the next 2 years, I'll be looking to purchase a MFR to househack. with the idea of reinvesting all of the cashflow to help scale.

You can increase returns with leverage (that is a mortgage) or with value add (renovations, additions etc).I think cap rates (rents minus expenses divided by purchase price) on commercial and industrial is higher with less work involved, but its more expensive than I can afford--so I know next to nothing about that land.

Purchase price: $220,000 Cash invested: $45,000 This is a 2 bedroom, 2.5 bathroom rental that I purchased.
