I want to entertain more offers because of the $6k in closing assistance, but I want to get out of this house and get on to the next. 

You'll want to enlist a CPA who specializes in real estate, trusts, & flow-through entities (this is a somewhat rare combination to find in a small/single-member firm, you may want to look at a larger regional firm to assist you if you can't find anyone who suits you at the smaller level).

Making such a blanket statement on item #2 is not reasonable (Im sure you will agree once reading my explanation) as the combined LTV plays a hudge role. if the first was $100k, and the second was $25k and the value was $300k, would you say no way to a $25k loan at risk in second position with $175k equity spread and a combined LTV of 41.6%?

This price hike suggests a competitive market, with supply increasing relative to demand by a notable 21.4 percent, resulting in a 1.7 months' supply of homes for sale.This recent development in the Charlotte real estate scene is likely influenced by a combination of factors, including a dip in mortgage rates in December and a nationwide increase in housing supply.

Arlington has a very strict area near the entertainment district for STR and requires registration.https://www.arlingtontx.gov/city_hall/departments/planning_d...Haslethttps://ecode360.com/41493162I like Haslet, but not sure there are any demand drivers for STR other than maybe the occasional race at the TMS.

HELOC is my first thought too but I am looking to combine them all into one mortgage and take a HELOC out on all 4 of my houses because they are just typical oklahoma town houses that only run in the range of probably 50k.

Some investors will combine STR with a winter long rental to make the #'s work.

That being said, this data combines several key areas around Boston proper to provide statistically relevant data; it is less likely for big swings from individual towns.
