When I began direct-to-owner marketing for multifamily (12-40 units), I realized it usually takes many months and touchpoints to build rapport with most sellers where they are willing to really open up about their property and financials. 

I would lean towards recommending that you pursue the deal - plus having the property remain in your family may be a net positive for you and your extended family regardless of the ultimate financial return. 

Based on what you shared you are not financially qualified to own real estate.

If you can get financial support to get a duplex/triplex, I would recommend this.

In our still relatively limited experience, seller financiers are usually looking to get a higher asking price in exchange for the favor of the private loan. 

@Serge Hounkponou Recommend you first figure out the property Class you want 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?

A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a accountant willing to work with you throughout the year.

With the limited access in Yardi, you won't be able to adjust account trees and create multiple customized financial statements. 

Prioritize your financial stability.
