when Joe Montana left SF for  KC  real estate doubled in SF and he came back and turned into a vintner and uber developer.. 

The top half of the duplex is a 4 bedroom / 1 full bath and the bottom is also 4 bedroom / 1 full bath.

Both units are occupied and we live out of town so it's a double wham...is it appropriate to as your tenants to do a mass showing on one day?

I feel as though we miscalculated something.One unit yields $400 in rent (1 bedroom) and the other yields $800 (3 bedroom).Total Rent: $1,200Duplex Price: $67,000Down Payment: $3,350Repair Estimate: $2,000Closing Cost Estimate: $1,500Total Investment = $6,850We factored in:Mortgage: $340Mortgage insurance (we would have a low down payment): $40Home owners insurance: $67Property tax: $113Vacancy savings: $60CapEx: $60Repairs: $60Lawn/Snow: $120There are no HOA dues.Total costs: $860So, our monthly cash flow should be $340.Annual cash flow $4,080Total Investment $6,850ROI: 59.5%I feel like this return is far too high.Is there something obvious we're missing?

Particularly one bedroom apartments?

The second floor has 3 bedrooms and should rent for $1,200. 

Ideally, I would like to find a company that is familiar with double-closing and assignments of contracts. 

We completed a remodel in our home adding 3 bedrooms and a shower to a half bath.I get this is probably a stretch but for the electrical work pretty much all of it can be easily traced through the attic the only thing that is concealed is the wire drop to the outlets and switches that were installed.

In my opinion, the only things that can justify price hikes are adding an extra bedroom or adding amenities to the property.

If so, doubling expenses to 31k including vacancies, repairs, 2x utilities would put it at a 11 cap rate.I would estimate lot rent as $350x 60m 189kAnd each home at 29k x9 261kTotal 450k, and these numbers are on the high side.Cap rate at 450k and most aggressive expenses including 10% vacancies and 10% repairs is 14.7Was appraised a few years ago at 550k before 20k homes flooded in our parish, and these were not one of them.
