This job should cost me about 1400$ for blown insulation.

@chrisSeveney should have some good advice as well.if this is NJ one thing I do know your in for a long slog and fairly costly

If we make a profit of $130k by selling the townhouse and minus all the cost (agent commission, selling cost, maintenance), then we use it to recast on the sfh, the sfh mortgage will be down about $800/month.

If you sell the house, your repair and improvement costs will be added to the cost basis, reducing your taxable profit.

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

Some banks, however, will allow you to do a "transfer of ownership" to move the property back into your personal name when refinancing, but it could involve additional costs and paperwork.Hybrid Approach:Some investors choose to buy property in their personal name, refinance with the bank for better terms, and then transfer ownership to an LLC after the refinance.

Also many title companies TODAY require a KNOWN notary.. so either they do it or they send you a vetted mobile notary that will cost you 150 to 200 for each sig.and yes this is why you dont buy the way the OP bought.. now he has a to chase his tail all to save a few bucks up front on title and escrow fees.. 

New constructions in the neighborhood are selling for a significant amount above construction costs (double or more the market value of the land).  

What made you interested in investing in this type of deal?

But it was like dealing with the mafia.
