Soooo many great opportunities down south.... weather was dreadful here in the northeast again today.

The answer will effect weather i sell it, as i'm buying a new primary, or the preferred route of renting it out, then selling it later to take advantage of 10 yrs of appreciation to then help payoff my new mortgage? 

Historically speaking, well-managed rental properties that were bought right weather recessions pretty well. 

How have you guys in the past on certain deals; determined whether a market that will have a new major employer moving into the area,(an example is the boon for residential and commercial real estate in Sparks Nevada ...

My suggestion as far as location, pick a state with sunny weather and a growing population.

Also winter weather is a great delay - ALL evictions are stayed Dec 18 - Jan 2, plus any day under 15 degrees, plus any day with inclement weather: https://www.cookcountysheriff.org/wp-content/uploads/2019/11/GO2019-01.pdf That alone racks up the sheriff backlog further.Sometimes if a tenant doesn't know anything, we can convince them to agree to move out in 30 days and the judge will then enter the order with a 30 day stay on that first court date.

Because of the weather and contractors schedule, it doesn't look like it can be completed in time.  

We've owned many 20 space parks over the years, and the key items to consider are:1) They can be hard to finance2) They can be hard to sell due to scale3) They can be hard to manage since you can't afford to hire very good talent4) They are too small to weather any big hits in cap-x issuesSo for this deal to work you'd want to have closer proximity to the park, city water and sewer, and no POHs. 

if that's the case, having an extra 20% in the deal from either buying low or adding value will be a big help in weathering the storm. this will make it that even if you ahve to sell, you could still earn some money or break even. additionally, with a multi it's generally more of a cash flow play, and if that's the case an economic dip won't be too big of a deal if you are cash flowing an acceptable amount with a buffer included. lastly if you get into a deal and have extra equity, you could bring in another investor in the future and "sell" the extra equity to them, while still staying in the deal. there are other options, like subject too's and rent to owns that may work here but for me buy low is the best defense. 

The weather was sunny and in the 60s last weekend, but yeah not necessarily a heavy crowd yet.
