It sucks but that's what is required when you own property.

I have two options 6.625% 30 year or 6.15% 15 yearI want to invest aggressively in the near future on more propertiesThe loan is only $110k and the monthly payment for 15 year is $563 and $750I will earn 2-3k a month in gross rental revenueThe property is in a declining population areaRecently rennovated, and all major things were relatively recently improved such as plumbing, the roof, a/c, electric, etc.Will require a lot of management as it is rent by the room so I may switch to a normal rental after 10 yearsI'm trying to find what will mathematically net me the most money in the long run.

Some may require a waiting period of one to two years before leasing is permitted, while others may prohibit rentals entirely as outlined in their bylaws.Always know the property’s potential for annual rental income and ensure the numbers work.

This loan doesn't require any certain length of ownership seasoning or equity. 

It all depends on what your requirement for cash flow is.

If they don't pay within the required timeframe, then I auction off the storage unit and wash my hands of it.

From fluctuating interest rates to evolving buyer demand, navigating today’s market requires flexibility and strategy.Are you seeing more opportunities in flips, rentals, or commercial properties?

Multi-family properties many times provide a better return per square foot than single family, which would be to your advantage as well.As long as you're mindful of the reinvestment requirements and purchase at least as much as you sold and use all of the proceeds, you shouldn't have any issues with this strategy.

It's definitely possible to get a loan as a foreigner but the rates will be high(er) and the downpayment required will be as well.
