I ran comps on the neighborhood to estimate an average price, subtracted all those repair costs and then subtracted an additional $30k or so to be conservative.

I typically subtract 3%, of the ARV.Realtor Fees: What is the commission you are willing to pay your listing agent (unless you are the listing agent) and the buyer's agent.

So to answer your question, if she gave you seller financing then the bank would subtract the amount that you owe her from the $70k.  

Subtract the operating expenses associated with the property from the gross income. 3. 

so you need to pay less than what retail price is if you want to make any moneyIf it needs 30,000 and work to get to retail value, subtract 30,000 and then subtract another 10,000, that might be of value to make some senseIf the agent think it's a good deal then have agent buy it and you go find another property and find an agent that knows what a good deal is preferably a buyers agentI piss off agents all the time so if you're upset about pissing off the agent don't worry about itBest of luck!

Next you’ll have to subtract any costs to make the lot ready.

The way its been explained to me is that the appraiser won't have a justification to either add or subtract $$ for the bomb shelter because of the lack of comps.

I looked quickly through Airbnb and it looks like room rentals are going from $25 to $75 per night during peak season.I'm guessing that cash flow could look something likeMonthly CashflowRoom Rental ($500 per month * 3 rooms ) + Airbnb Room Rental ($50 per day * 20 days [subtracting days for flip days]) - Expenses ($1k) = $1500 + $1000 - $1000 = $1500Net Annual CashflowRoom Rental ($500 per month * 3 rooms *12 months) + Airbnb Room Rental ($50 per day * 180 days per year[6 month per year]) - (8.5% hotel tax + 1 sales tax) - $125 annual regisitration fee for home sharing + Using the Airbnb room as regular room rental for remainder of the year ($500 per month * 6 months) - Expenses ($1k * 12 months) = $18000 + $9000 - $855 - $125 + $3000 - $12k = $17020Start-Up CostsFurnishing common areas and Airbnb room plus purchasing pots, pans, utensils, garbage cans, etc - $5000Acquiring property with traditional financing - $30k or soI will kick the tires with lease optioning as a potential way of bringing down financing costsBreaking Even on Start-Up Costs$5000 to $35k initial start-up costsAssuming $500 per month lease option = ($5000 + 500)/1500 per month profit = 3.66 rounding up to 4 months to break evenTraditional financing = $35k/1500 = 23.33 months rounding up to 24 months or two years to break evenAssumptionsPhilly has a law that you can only rent on Airbnb for 6 months per yearI went with the higher purchase amount $150k but with the lower room rental range and middle Airbnb daily rateI'm assuming that the property will have 4 bedroomsIf my assumptions and numbers work than Philly definitely looks interesting as a vacation rental market.

Probably not $70,000, because that would leave only $10,000 net profit, and after subtracting resale closing costs, that's not enough profit to fool with.

With my math and subtracting the $100 that I gave them on Monday that was said to make us even I came up with $311....
