A bedroom in A Manhattan apt may go for 65-95 per night, because comparable square footage in a hotel would be $200+.

Contrary to some advice above, always pull permits when you add a bedroom, bathroom, or square footage so it goes on the assessors website.

Property #2Lake front but in a cove with not as good of a viewIt has the right amount of square footage, and many new things (new deck, dock, new exterior paint, etc.)These are friends from church who are really motivated to figure out a deal because she lost her job and they will end up in foreclosureShe mentioned us taking over the mortgage payments without a down payment - however, they are 2800 per month which is more than double what we are paying nowHer house is valued in the low 300,000'sIf we were able to make this work, we could hold onto our current residence and rent it to grow our portfolio which would be great with not too many years left on the mortgageWhat I would like to offer would be us paying what we would be comfortable per month (i.e. more like $2300) but then wonder how that would work for themIf they were to go into a short sale, that would require us to sell our house to get the equity for the down payment and I'm not 100% sure I want to do thatPlease help with any and all ideas.

Then count up the square footage of self storage currently in the market.

if adding an additional bath or square footage you should always use permits, in the event you want to sell the home and get top dollar for it down the road, you'll need to have those additions permitted or else they won't be accounted for when it comes to the appraisal, a buyer may say sure the bath looks good we will pay as if it is a 3/2 (example) but the appraiser will not appraise it as such and may burn you if you can't get the valuation you need

You might find some renters need 2-3K in square footage.  

Because now you can write off a percentage of your electric bill, rent, heat, mortgage, depreciation, certain repairs ect or take the new simpler deduction based on the sq footage of the office.  3. 100% car deductions:  Please reread my intro statement for this bullet point, because by claiming a 100% deduction he is basically daring the IRS to audit him. 

So..... this might be a sketchy idea but I plan on adding a bathroom to the current sq footage and a carport on the back access to the property.My cost is materials and permits etc.

@Igor AvratinerIn my case, these were developments of basically identical 4-plexes with the same layout, square footage, etc.

., minimum net clear opening width when opened, net clear opening height when opened and overall net clear square footage).
