Starting out need help

[Cordell Hughes]

Me and my wife are looking to get out this 800/month rent. I had to idea to do a Reno on a mobile home i already own with no monthly payments. I intend to eventually rent to mobile home out regardless. The mobile home just in need of cosmetic things. I think the most expensive thing to replace would be both bathrooms they both could use a new bath/shower combo in both of them. Its also closer to my job and cut my driving time from 45 min to a 1 hr depending on traffic to 16 min to 20 min tops. It make sense all the around far as trying to save money to invest because we currently do not have any. On the other hand her Granddad who owns a business and done well for himself in his lifetime(80 years old) he said we should go get a mortgage on a home and find something around 600 a month or lower because of the low interest they are offering because of the Covid-19. It makes since also, but i really need some expert options on the situation who actually invest in real estate for a living. So i guess the question i am asking is...If you were a young married couple who are also first time home buyers. which would seem like to best choice to start your investing career???  

Thanks for any comment or info that you may have.
