I am trying to strike a balance between a market that can deliver month-to-month cashflow (after debt service) while enjoying some level of appreciation.

Hope this helps, it is all about balancing costs verses amenities for the your rentals.

Also, you may find that such programs involve two loans, one for probably up to 70% of the purchase price and the second lien for the balance needed which usually comes at an extreme price. 

For example, there are prepaids that end up resulting in my having a larger principal balance than I currently have, in addition to paying the refinance fee.Now I'm trying to determine if the savings from the lower payments will be more than the cost of the higher overall loan payoff.

Here are some of the numbers:After Repair Value $90,000List Price $79,900Monthly Rent $775 (low capex/vacancy/will self manage)Offer $69,900EMD $1,000Buyer to pay all closing costs/attorney fees (should be less than $3,000)$10,000 downPayments at 5% based on 30yr Amortization schedule10yr term on repayment/ Balance due in full at year 10.Thoughts on this structure?

You should add your data once and get the full benefit end to end of this:Rent Cycle Balance your books with full general ledger accountingDownload reports on-demandTrack charges and paymentsCollect payment onlineVacancy Cycle Free marketing websiteSyndicate rental listingsReceive rental applications onlineRun credit and background checksMaintenance Cycle Tenant access to responsive mobile siteSubmit work orders electronicallyAttached photos and documents to requestsEfficient reporting

Vast majority were the "make me a good enough offer and I'll sell" types, many were grossly over priced (value-$200k,  Mtg balance-$280k, Ask-$290K), some were wholesalers, and some just fake/non existent. 

The additional property reserves are determined by the sum of all the mortgage balances on all those properties which are not your primary:2% of the aggregate UPB 1 to 4 properties4% of the aggregate UPB 5 to 6 properties6% of the aggregate UPB 7 to 10 propertiesSo if you had 3 other investment properties with an aggregate unpaid principal balance (UPB) of $300k you would need $6,000 in reserves for those properties.  

Their marketing budget balance sheet will no doubt feature website and domain maintenance, SEO optimisation, the cost of employing marketing staff, advertising and public relations to name a few.But where does networking fit in?

@Logan TurnerI don't see anyone asking the fundamental questions of whether or not you want to transfer title...just assuming, but I would suspect that the the balance is a re-fi...you can't transfer title: i.e. you can't own this house unless that is settled.
