If buying from an HOA sale or sale from a 2nd mortgage - these can be overturned by a judge (first mortgage sales can be also but not as often) - so know what you are getting.4.

I'm was going to refinance my home from my mortgage company so I could do some home repair but I decided I don't want to I have not schedule a closing date but i have singed some paperwork how do I back out of it ?

If you can  originate your construction loan at time of settlement  with the approvals in hand you should come out ahead if the option exists.

Here's a summary of my situation as an example: The unit I currently live in would rent for $2200My second unit is currently rented for $2700I rent my garages out for $350For the next duplex I would live in one unit & rent the other for $2200 I currently get paid $80k a year or $6667 per month.75% (2200+2700+2200) + 350 + 6667 = $12342 per month in incomeMy current mortgage is 2950, my next would be 3300, and my student loan is 250 = $6500 total debt.6500/12342 = 52.7% DTI

One needs to be realistic about investing, making money, and investing where the opportunities exist. 

I am currently house hacking a duplex with air bnb to cover our mortgage!

Even if this means paying out of pocket to cover the mortgage/expenses.How long has the property been marketed?

How do I go about getting approved when I am already maxed out on getting another mortgage..? 

If I did an FHA loan and paid little down, the mortgage payments would be insanely high right?

Prop 1 SFH: mortgage amount around $950, rented at $2175Prop 2 SFH: mortgage amount around $900, rented at $1725Prop 3 Duplex: mortgage amount around $1000, rented at $1400($700/side)Prop 4 L/O Duplex: mortgage around $800, rented at $1850($925/side)What would you do here?
