Is it worth it to put in central heat and air?

Hi Kanaam,To start, focus on financing—U.S. lenders may require higher down payments (often 25-35%) for foreign investors.

The insurance companies might require this. 

The bank said they require 90% owner occupancy and since our HOA is only 5 units, we only have 80% of units occupied by owner. does anyone have any suggestions on any banks or credit unions where this may not be an issue? 

Quote from @James Jefferson: Hi, I have a family member that had a reverse mortgage on their property it's a 3b 1b 1 acre of land heats by oil no hvac and on well water.

Are there any lenders or resources out there that can provide DSCR loans or other types of loans that are less than 100K and don't require prior ownership history?

I require a real estate attorney to draft a wholesale contract (assignment agreement) for two properties in St.

If you're buying a true investment property (meaning you wont live in it), FHA is completely off the table and Conventional/DCSR will require 15%+ down.

So, anyone who tells you to worry about the heat in AZ doesn't get it.
