If they offered seller finance to us, those funds could then be used to pay for the lease at our home if we swap however they are retired, what about tenant screening amongst other things, not sure what type of deal structure is best for this scenario but if anyone can guide me with any feedback is greatly appreciated.

If you have multiple properties, you would pay more in the long-run buying insurance ever time.

Charge what you need but be sure and pay it off before the introductory rate expires. 

Did a "hard money loan" with family using gift tax exemption and trust as collateral (despite what Dave Ramsey says, my father and I have an incredibly strong investing and personal relationship).

A self-directed 401(k) plan offers the small business owner one of the last significant tax benefits.

I have $50K in debt with a payment of about $1220 in a consolidation loan that will be payed off in 3 years.

However, I have a few concerns:Pros:Living condition: 1400 sqft → 1700 sqft with some boutique featuresThe rental market seems good in this area.Another property is added to my existing real estate portfolio, which currently includes two other properties.Cons:Interest rate: 7% - No guarantee of decreasing the rate, which means there might be no opportunity for refinancing in the future.The current home is too new to be rented out.People often say not to buy property in Chicago due to high taxes and low appreciation.There’s no necessity of moving since I have a decent primary home.Any professional advice would be helpful. 

I would be in it for cash flow and tax write offs but the how strong is the rental market?

You will need 20-25% down and a commercial loan for the rest.Most lenders will want to lend to an LLC with you personally guaranteeing the loan.Typically, each MFR would be purchased under its own LLC, for liability purposes.Each LLC would then also need its own bank accounts for collecting rents and paying expenses.

I see a lot of unnecessary risk in investing in another country.If you still want to do it, I would start off with something on the lower end that is still nice to see how it goes for a couple of years before making a major investment out of country.I would thoroughly research all expenses such as taxes insurance, permits etc.
