Let's assume the financials in the package are good for a moment (they probably are not) AND that you either do not or do achieve the broker's pro forma:If you purchase this asset, achieve ONLY the 'current' NOI, grow NOI 2% per year, and exit at a 5% cap at the end of Year 6, you will have a 4.8% unlevered IRR. 

Keep in mind, it would be in your best interest to go for as high as 4 units on each purchase to maximize your door count. 

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

Who owns the solar panels and what's my liability if I continue with the purchase?

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. 

@Chase AlexanderRecommend 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?

Do your research and see what fits you best - best of luck my friend 

The only additional thing that needs to happen is make sure appraiser makes note of why the value increase in as is vs previous purchase price.

As I build my career as an agent, I’m also passionate about real estate investing, specifically with a goal of purchasing multi-family, buy-and-hold properties where I can live in one unit and rent out the others.I’m here to network, learn from experienced investors, and contribute to the community.

Just basic face to face talks with people soon to be friends.
