Some of them have said the rule only applies to specific types of loss others are saying it's any paid loss. 

I have never purchased an investment property, have minimum knowledge besides what I've studied on, and have zero hands on experience.

We handpick properties, and guide them through the purchase, rehab, and management of the properties.  

When you move out of the city, the debt on the current house will negatively affect your ability to borrow to purchase a different place.  

This would be better than learning a large purchase may not help you tax-wise come filing time. 

You have a higher purchase price but lower interest rate.2.

@Jim Johnson yes you can ask for personal connections but also set up Alert words so you can focus on your specific area of interest

If we purchase any of these as an investment property, we would need 20% down, however will have tenants immediately after purchase. 

Options are to take out a loan for the 25% and just purchase or co-sign a multifamily or just co-sign on a SFH so they can get the 5% down, no loan needed, there wouldn't be any real benefit to me and my husband as we would be assuming the debt but we would be helping our kids out. 

Get specific and refine your investor avatar.
