Having the investment property in an LLC or having the investment property tied in with my primary home?

Given the rate environment (I am at 4.25% for 30 yr fixed jumbo $695k remaining with estimated house value around $1.15m) I am interested in in doing a cash out refinance.  

Wholesalers add no value to the real estate world... you tie up a sellers property asking unrealistic prices, your sales do not hit the MLS so you do not boost values in an area and most are uneducated hacks. 

(Now it is a lot with some (non-human) charred remains to clean up.)

I have done this in originating a 90% purchase price loan in which the remaining 10% is financed from another lender.

would be appreciated - my numbers for this property are here below:Market Value $320k; Zillow says the home value will stay the same for the next year though (it has tapered off in the last year)Remaining Principal: $110k5BR, 3BA + Basement, 2500 sq ftCurrent Rent: $1950/moExpenses: $1900/mo (5% vacancy rate, estimated expenses, $500 HOA, $4800 in property taxes, $1800 in insurance, $900 P&I included)Located in Suwanee, GA:Great Schools Rating: 9 (High School), 8 (Middle School), 10 (Elementary School)Niche Grade A+; Public Schools A+, Jobs A, Crime/Safety B, Cost of Living C+24% Rent, 76% Own#2 Best Public Schools in Georgia#5 Best Place to Raise a Family in Georgia

But you are tying it up in a highly illiquid form for a long time.Bottom line: I'm not seeing how this property is going to make you money. 

They can not only cost you an arm and a leg if you follow their standard pay off schedules, but they can seriously undermine your loan approval chances with a lender.If your debt is tied to a fixed mortgage, I wouldn't worry about it as much as long as your overall DTI is low & payments are easily made.

How do I input the front end loss of rent for that unit and then apply the rent for the remaining time?

Rates and inventory remain low, demand remains high.However, not all markets and submarkets are in the same position.
