But I guess it's not completely out of the question. 

Guess what?

Trying to figure out the “real” cost of installing a new central AC unit and replace existing old furnace.This is in San Jose, CAHome is 1600 sq ft - 2 story Got quotes that range from 8.5k to 15kI guess the need is a 3.5 ton compressor and a 2 stage energy efficient furnace.

Only sent out about 150 so far and around 8pm on a Saturday night i got a call from a executive "executive general realty" im guessing this is a realtor but i returned the call but didn't get a answer but i left a voicemail.

My guess is you need permission to move it.

All right, I guess I'll drop the on-site handyman idea.

I guess I’m not going to benefit a lot in taxes.

Because the buildings are nice and have 3/2 or 3/3 layouts, I'm guessing tenants stay longer than in 2/1s.

Based on all that you've said in the way of "what ifs", and taking into consideration the following:a - $1000 rent - expenses (guessing 1/3 with no mortgage) ~ $700/month in CFb - CF would then be around $8,000/yearc - If home is worth $160k, and you sold it for $155k, minus closing costs (about 10%), you could walk away with around $140kd - If you kept the property, and the CF/year, it would take you 17.5 years for the CF to equal the Profit if you sold it now.e - If you invested the $140k into 20% down payments for 7 units worth  $100k/ea, and each (financed) property netted you $600/month in CF, you could have an actual income (not gross...net) of over $4k month.

But I guess that’s why tenants are tenants and owners are owners.
