Converting the sunroom into a bedroom would cost 4k-5k. 

First, all first flips take 2-3x as long as you think and cost 2-3x as much as you think.

If you are planning on buying it with a smaller down payment, that will also increase your mortgage costs as you are borrowing more and also need mortgage insurance.The price of the home (from the seller's perspective) is based on market value and condition, not on whether or not it matches the 1% rule.   

The average single-family home may cost $10,000 and that's a new install.

One of my properties cost me a little more, but the other two were less than what I was paying with foremost insurance.

Tenant’s failure to maintain any item for which Tenant is responsible shall give Landlord the right to hire someone to perform such maintenance and charge Tenant to cover the cost of such maintenancePremises defined in the lease as follows:  Landlord rents to Tenant and Tenant rents from Landlord, the real property and improvements described as: address of the rental property (“Premises”).1.

This, however, changes not only from county to county but also by neighborhood, zip code, school district, etc.Another change we are witnessing in real-time is increased seller’s concessions, which can go towards financing closing costs or buying down the interest rate.

My current primary ( scenario 1) Keep the primary for the life of the loan ( current rate is 4.5 so i dont see my self refinancing anytime soon)current home value 1,150,000Loan amount 935,000appreciation estimate 5% per year after a 28 year hold and the house is paid off I would have a house worth 4,312,000$my current mortgage is 6125$ ( piti) included My second option( scenario 2) Sell the house, walk away with $150 ,000 ish in hand and put that into a low cost index fund Rent a house elsewhere for about 3000$ ish and take the extra 3000$ im saving everymonths from not having to pay my mortgage and puting that money in the index fund as well I ran the numbers on both of these scenarios and doing what I mentioned above would break even at about 28 years meaning my stock account would be worth 4.3 million just like my house would , but the only is that holding a house for 28 year would mean 28 years of property taxes, loan interest ,home insurance and repairs etc whick I calculated to be about 1,200,000$ at minimum which raised my eyebrows to say the least Also i understand that each of these options ( stock market vs real estate ) will have there tax consequences ( long term capital gains) so any thoughts on that would be appreciated as well.
