So I had to leave them.

Can I leave them off of the original purchase since they are gifting me the money (6 figures) or do they need to be on the original deed and then when I get the mortgage remove them?

If you need to leave in less than a year, you need a really good reasonbecause Fannie/Freddie/FHA/VA and other secondary market makers don't like foryou to get owner occupied loans and then not stay in the property.

Though the property and surrounding areas look nice in the pictures, the doors and windows has bars which concern me.I am just starting our my RE investment journey and all help is greatly appreciated.

That ends up leaving a void that's filled by unprofessional, and in some cases outright criminal operations there in the PM space.

Me and my girlfriend are currently saving to purchase a home within the next year or so to start house hacking, my concern is how signing the lease option to purchase contract will affect our eligibility for first time home buyer programs? 

Even with long-term tenants, you’ll still have turnover costs when they leave.

Unfortunately, I tend to agree that they really are not concerned with whether or not you have to cancel bookings. 

Also, when it comes to these infrastructure items you are concerned about, learn more about the "options".

If the call is important, they can leave a message and/or text, and state that in your answering message.
