For example, where can I find info that New York City is planning to add a subway line in XXX neighborhood and is set to complete construction in 2030.

If you bought Oct 2020 via FHA, then you can't buy a new primary residence until Oct 2021 or later this year due to the occupancy requirements (unless you fall in one of the outlier exceptions like you move more than xxx miles away etc)You're looking at 15% down minimum generally for an investment property condo or SFH.

Is it a must to be xxx miles from the airport?

The phone calls started about a month ago, asking me if I wanted to sell my property at address XXX. 

We send a letter that states something to the effect that their current rent is $300 below market and it will increase by $XXX amount starting May 1, 2021.As a new owner, make sure you address maintenance issues etc. before you increase rents.

Another strategy to consider is: Could you buy this MH, do some minimal fixup, raise the price to $XXX, and sell to someone on a Rent-To-Own Basis!

My goal is to eventually become financially able to leave my full time job (96,xxx in 2020) will increase to 100k this year, I feel behind from all my friends (28yrs old) while there purchasing houses and new cars and everything, but I think having this 100k + paid off house has me in a better financially situation.

@Kaylee Walterbach As a 24-year old who recently syndicated their first multifamily deal, while being an active duty Air Force officer, I believe it's a willingness to consistently do what others won't and a compulsion to get around the right people.

@Charles ClarkAlthough each state is different, you can search for "XXX County appraiser website" or "XXX County RE taxes"Some will let you search by owner, or address or parcel number.You can also look for county GIS, and usually pull information from there or even link directly to other websites like the tax bill or warranty deed.You can also usually find a tax calculator which can be useful for estimating taxes on an "improved" lot that may have previous been unimproved (i.e. 2021 tax bill was for a lot so it's like $800, but the improved lot is a $900,000 home so you know the tax bill will be higher - now you can get the number before waiting for the new bill).For example, here's Dallas County TX:https://www.dallasact.com/act_webdev/dallas/searchbyproperty.jsp

"Seller X agrees to sell property at 123 Anywhere Ave Units A - ZZ for $X,XXX,XXX on or before (today) + 90 days to Buyer Ryan James or Assigns."
