I do not have the $80k for the down payment.

Several factors can increase or decrease the adjusted basis, says McGuff.Increases in adjusted basis can result from:The cost of additions and improvements to the houseMoney spent to restore the property after damages or lossLegal fees incurred in relation to the propertyDecreases in adjusted basis can result from:Receipt of insurance payments due to a casualty loss or theftTax credits for home energy improvementsIf you sold your primary home last year, there’s little you can do to avoid capital gains tax liability when you file taxes this April, Liddiard says.

You think I should just keep on making minimal payments or should I go ahead and pay down the 20%.  

Understanding local market trends, demographic shifts, and future development plans can provide investors with a competitive edge.

Purchase price: $85,000 Cash invested: $46,500 This property was just acquired, part of the investment was in leu of payment for work completed on another project.

With that type of experience, I might target a fix/flip or HML that has experience triggers keeping your costs low and maybe even something like deferred interest payments or bundled fees.

Having a mortgage payment plus needing to pay an extra $1k/mo towards this TSP loan will crush any cashflow you had hoped for.  

PAYMENT DISBURSEMENTS - Incoming rents would come into a general rent account, replenish the maintenance fund for any expenses incurred through the month, take the PM fee, and then disburse the rest into the owners account.

If I take those out like a HELOC how do I actually pay that loan back as I'll still have a monthly payment for that loan? 

If you are locked in at a three-handle, I would HELOC the equity and use it as a down payment on a new deal.
