We did a pretty extensive renovation to the house- kitchens/baths gutted, new appliances, new HVAC, new plumbing, new windows/exterior doors and new lighting.

Vinyl plank throughout except for kitchen which is tile.

Previous sales history - In June 2008 my house sold for $1,425,000 (with an unfinished carriage house, small 90's kitchen that didn't fit the house style at all, and no master suite. 

Please note, this includes: the roof, plumbing, electrical, HVAC, kitchen, etc.We had another set of contractors who gave us a quote $130,000.

If you put in an hour a night then in a couple months you will be able to have a great idea of what a property would sell for just by knowing the size, bed/bath, and seeing some pictures of the kitchen and bathrooms.

I have entered estimates for repairs and will possibly begin an offer at $105K.Here is a link to the Google photo album of the interior of the house - https://photos.app.goo.gl/mMoCL5Erq4hcqAdP9The figure for Plumbing is for each bathroom (2 1/2) as a full remodel.The figure for Doors includes reframing with lumber and doors throughout the house and windows, which also includes drywall, mud and other appropriate items.The figure for Cabinets/Countertops is for an entirely new kitchen with appliances.I appreciate your feedback.

I guess I’d worry about a “too many cooks in the kitchen” situation .

I work in renovation sales: primarily kitchen and bathroom renovations, so I meet with many individuals who are looking to put their home up for sale in the near future.From my understanding, there is no such thing as a 100% ROI for remodeling. 

(Well, it would be once the 6-plexes are fully rented.)Also consider what you have to maintain for each property:Office: 1 Roof6-plexes: 2 RoofsOffice: 4 HVAC units6-plexes: 12 furnaces + 12 AC window unitsOffice: 2 kitchenettes (Fridge, sink)6-plexes: 12 full kitchens (Above, plus range/oven, vent/hood, dishwasher, etc.)Office: 4 bathrooms6-plexes: 12 bathroomsA couple more confounding factors: The office building is built in 2005 and located in a suburb of a major metropolitan area currently experiencing substantial growth.

Then we will have to go with the Gas forced unit with the trunking or you could have 2 window unitsBid for remodelingDemo upstairs kitchen and tub and bathroomremove all debris from in the crawl spacekitchen down stairsremove tub shower down stairsremove old wall furnaceremove old carpethaul away all trashWindows and doorsall windows need replaced 14 total, the upstairs windows need to be special glass because of the coding from the building depart for height restrictionsFront door need replacedAll interior doors need replacesUpstairsWalls will need to be removed and replaced to convert to a 4-5 bedroom homeAll new interior doors need replacedPlumbing removed there will be no bathroom upstairsBathroomA brand-new bathroom will be installed with a tub shower, vanity, toilet,an faucets.
